Installing Windows Server as Virtual Server – Get Certified Get Ahead

 

Intel hardware is required. See also Chapter 14, Known Limitations. Linux hosts bit. Includes the following:. See Section 2. However, the formally tested and supported Linux distributions are those for which we offer a dedicated package.

Oracle Solaris hosts bit only. The following versions are supported with the restrictions listed in Chapter 14, Known Limitations :. Note that any feature which is marked as experimental is not supported. Feedback and suggestions about such features are welcome. If you have installed software before, installation should be straightforward.

On each host platform, Oracle VM VirtualBox uses the installation method that is most common and easy to use. If you run into trouble or have special requirements, see Chapter 2, Installation Details for details about the various installation methods. Base package. Extension packs. Additional extension packs can be downloaded which extend the functionality of the Oracle VM VirtualBox base package.

The extension pack provides the following added functionality:. The virtual USB 2. The virtual USB 3. Host webcam passthrough.

See Section 9. Disk image encryption with AES algorithm. Cloud integration features. Oracle VM VirtualBox extension packages have a. To install an extension, simply double-click on the package file and a Network Operations Manager window is shown to guide you through the required steps. To view the extension packs that are currently installed, start the VirtualBox Manager, as shown in Section 1.

From the File menu, select Preferences. In the window that displays, go to the Extensions category. This shows you the extensions which are currently installed, and enables you to remove a package or add a new package.

Alternatively, you can use the VBoxManage command line. See Section 8. On a Windows host, in the Programs menu, click on the item in the VirtualBox group.

On some Windows platforms, you can also enter VirtualBox in the search box of the Start menu. You may want to drag this item onto your Dock.

Alternatively, you can enter VirtualBox in a terminal window. This window is called the VirtualBox Manager. The left pane will later list all your virtual machines. Since you have not yet created any virtual machines, this list is empty. The Tools button provides access to user tools, such as the Virtual Media Manager.

The pane on the right displays the properties of the currently selected virtual machine. Since you do not have any machines yet, the pane displays a welcome message. Click New in the VirtualBox Manager window. A wizard is shown, to guide you through setting up a new virtual machine VM. On the following pages, the wizard will ask you for the bare minimum of information that is needed to create a VM, in particular:.

For example, Windows 10 with Visio. The Machine Folder is the location where VMs are stored on your computer. The default folder location is shown. The supported OSes are grouped. If you want to install something very unusual that is not listed, select Other. This is particularly important for bit guests. It is therefore recommended to always set it to the correct value. The amount of memory given here will be taken away from your host machine and presented to the guest OS, which will report this size as the virtual computer’s installed RAM.

Choose this setting carefully. The memory you give to the VM will not be available to your host OS while the VM is running, so do not specify more than you can spare.

If you run two VMs at the same time, even more memory will be allocated for the second VM, which may not even be able to start if that memory is not available. On the other hand, you should specify as much as your guest OS and your applications will require to run properly. A guest OS may require at least 1 or 2 GB of memory to install and boot up. For best performance, more memory than that may be required. If insufficient RAM remains, the system might excessively swap memory to the hard disk, which effectively brings the host system to a standstill.

As with the other settings, you can change this setting later, after you have created the VM. There are many and potentially complicated ways in which Oracle VM VirtualBox can provide hard disk space to a VM, see Chapter 5, Virtual Storage , but the most common way is to use a large image file on your physical hard disk, whose contents Oracle VM VirtualBox presents to your VM as if it were a complete hard disk. This file then represents an entire hard disk, so you can even copy it to another host and use it with another Oracle VM VirtualBox installation.

To create a new, empty virtual hard disk, click the Create button. You can pick an existing disk image file. The drop-down list presented in the window lists all disk images which are currently remembered by Oracle VM VirtualBox. These disk images are currently attached to a virtual machine, or have been attached to a virtual machine. Alternatively, click on the small folder icon next to the drop-down list.

In the displayed file dialog, you can click Add to select any disk image file on your host disk. Click the Create button. This wizard helps you to create a new disk image file in the new virtual machine’s folder.

A dynamically allocated file only grows in size when the guest actually stores data on its virtual hard disk. Therefore, this file is small initially.

As the drive is filled with data, the file grows to the specified size. A fixed-size file immediately occupies the file specified, even if only a fraction of that virtual hard disk space is actually in use. While occupying much more space, a fixed-size file incurs less overhead and is therefore slightly faster than a dynamically allocated file.

For details about the differences, see Section 5. But the image file must be large enough to hold the contents of the guest OS and the applications you want to install.

For a Windows or Linux guest, you will probably need several gigabytes for any serious use. The limit of the image file size can be changed later, see Section 8. After having selected or created your image file, click Next to go to the next page. Click Create , to create your new virtual machine. The virtual machine is displayed in the list on the left side of the VirtualBox Manager window, with the name that you entered initially. After becoming familiar with the use of wizards, consider using the Expert Mode available in some wizards.

Where available, this is selectable using a button, and speeds up the process of using wizards. Go to the VirtualBox VMs folder in your system user’s home directory. Find the subdirectory of the machine you want to start and double-click on the machine settings file. This file has a.

Starting a virtual machine displays a new window, and the virtual machine which you selected will boot up. Everything which would normally be seen on the virtual system’s monitor is shown in the window. See the screenshot image in Chapter 1, First Steps. In general, you can use the virtual machine as you would use a real computer. There are couple of points worth mentioning however.

This wizard helps you to select an installation medium. Since the VM is created empty, it would otherwise behave just like a real computer with no OS installed. It will do nothing and display an error message that no bootable OS was found. In the wizard’s drop-down list of installation media, select Host Drive with the correct drive letter.

In the case of a Linux host, choose a device file. This will allow your VM to access the media in your host drive, and you can proceed to install from there. If you have downloaded installation media from the Internet in the form of an ISO image file such as with a Linux distribution, you would normally burn this file to an empty CD or DVD and proceed as described above. In this case, the wizard’s drop-down list contains a list of installation media that were previously used with Oracle VM VirtualBox.

If your medium is not in the list, especially if you are using Oracle VM VirtualBox for the first time, click the small folder icon next to the drop-down list to display a standard file dialog. Here you can pick an image file on your host disks. After completing the choices in the wizard, you will be able to install your OS. If you are running a modern guest OS that can handle such devices, mouse support may work out of the box without the mouse being captured as described below.

But unless you are running the VM in full screen mode, your VM needs to share keyboard and mouse with other applications and possibly other VMs on your host. After installing a guest OS and before you install the Guest Additions, described later, either your VM or the rest of your computer can “own” the keyboard and the mouse. Both cannot own the keyboard and mouse at the same time. You will see a second mouse pointer which is always confined to the limits of the VM window.

You activate the VM by clicking inside it. By default, this is the right Ctrl key on your keyboard. On a Mac host, the default Host key is the left Command key. The current setting for the Host key is always displayed at the bottom right of your VM window. Your keyboard is owned by the VM if the VM window on your host desktop has the keyboard focus.

If you have many windows open in your guest OS, the window that has the focus in your VM is used. This means that if you want to enter text within your VM, click on the title bar of your VM window first.

To release keyboard ownership, press the Host key. As explained above, this is typically the right Ctrl key. For technical reasons it may not be possible for the VM to get all keyboard input even when it does own the keyboard.

Your mouse is owned by the VM only after you have clicked in the VM window. The host mouse pointer will disappear, and your mouse will drive the guest’s pointer instead of your normal mouse pointer. Note that mouse ownership is independent of that of the keyboard. Even after you have clicked on a titlebar to be able to enter text into the VM window, your mouse is not necessarily owned by the VM yet. These tools make VM keyboard and mouse operations much more seamless.

Most importantly, the Guest Additions suppress the second “guest” mouse pointer and make your host mouse pointer work directly in the guest. Some OSes expect certain key combinations to initiate certain procedures.

The recipient of these keypresses depends on a number of factors, including the key combination itself. Host OSes reserve certain key combinations for themselves. As the X server intercepts this combination, pressing it will usually restart your host graphical user interface and kill all running programs, including Oracle VM VirtualBox, in the process.

If, instead, you want to send these key combinations to the guest OS in the virtual machine, you will need to use one of the following methods:. Use the items in the Input , Keyboard menu of the virtual machine window.

However, the latter setting affects only Linux guests or Oracle Solaris guests. This menu also includes an option for inserting the Host key combination. Use special key combinations with the Host key, which is normally the right Control key.

This is a global setting for all virtual machines and can be found under File , Preferences , Input. A soft keyboard can be used to input key combinations in the guest. While a virtual machine is running, you can change removable media in the Devices menu of the VM’s window. But as the Settings dialog is disabled while the VM is in the Running or Saved state, the Devices menu saves you from having to shut down and restart the VM every time you want to change media.

Using the Devices menu, you can attach the host drive to the guest or select a floppy or DVD image, as described in Section 3. You can resize the VM’s window while that VM is running. When you do, the window is scaled as follows:. If you have scaled mode enabled, then the virtual machine’s screen will be scaled to the size of the window.

This can be useful if you have many machines running and want to have a look at one of them while it is running in the background. Alternatively, it might be useful to enlarge a window if the VM’s output screen is very small, for example because you are running an old OS in it.

The aspect ratio of the guest screen is preserved when resizing the window. To ignore the aspect ratio, press Shift during the resize operation. See Chapter 14, Known Limitations for additional remarks. If you have the Guest Additions installed and they support automatic resizing , the Guest Additions will automatically adjust the screen resolution of the guest OS. For example, if you are running a Windows guest with a resolution of x pixels and you then resize the VM window to make it pixels wider, the Guest Additions will change the Windows display resolution to x Otherwise, if the window is bigger than the VM’s screen, the screen will be centered.

If it is smaller, then scroll bars will be added to the machine window. When you click on the Close button of your virtual machine window, at the top right of the window, just like you would close any other window on your system, Oracle VM VirtualBox asks you whether you want to save or power off the VM. Save the machine state: With this option, Oracle VM VirtualBox freezes the virtual machine by completely saving its state to your local disk. When you start the VM again later, you will find that the VM continues exactly where it was left off.

All your programs will still be open, and your computer resumes operation. Saving the state of a virtual machine is thus in some ways similar to suspending a laptop computer by closing its lid. Send the shutdown signal. This will send an ACPI shutdown signal to the virtual machine, which has the same effect as if you had pressed the power button on a real computer.

This should trigger a proper shutdown mechanism from within the VM. Power off the machine: With this option, Oracle VM VirtualBox also stops running the virtual machine, but without saving its state. This is equivalent to pulling the power plug on a real computer without shutting it down properly.

If you start the machine again after powering it off, your OS will have to reboot completely and may begin a lengthy check of its virtual system disks. As a result, this should not normally be done, since it can potentially cause data loss or an inconsistent state of the guest system on disk. As an exception, if your virtual machine has any snapshots, see Section 1. In that case, powering off the machine will not disrupt its state, but any changes made since that snapshot was taken will be lost.

The Discard button in the VirtualBox Manager window discards a virtual machine’s saved state. This has the same effect as powering it off, and the same warnings apply. VM groups enable the user to create ad hoc groups of VMs, and to manage and perform functions on them collectively, as well as individually. Select multiple VMs and select Group from the right-click menu. This command creates a group “TestGroup” and attaches the VM “vm01” to that group.

Detach a VM from the group, and delete the group if empty. For example:. This command detaches all groups from the VM “vm01” and deletes the empty group. This command creates the groups “TestGroup” and “TestGroup2”, if they do not exist, and attaches the VM “vm01” to both of them.

With snapshots, you can save a particular state of a virtual machine for later use. At any later time, you can revert to that state, even though you may have changed the VM considerably since then.

A snapshot of a virtual machine is thus similar to a machine in Saved state, but there can be many of them, and these saved states are preserved. To see the snapshots of a virtual machine, click on the machine name in VirtualBox Manager.

Then click the List icon next to the machine name, and select Snapshots. Until you take a snapshot of the machine, the list of snapshots will be empty except for the Current State item, which represents the “now” point in the lifetime of the virtual machine.

Take a snapshot. This makes a copy of the machine’s current state, to which you can go back at any given time later. The snapshots window is shown. Do one of the following:. Click the Take icon. Right-click on the Current State item in the list and select Take. In either case, a window is displayed prompting you for a snapshot name. This name is purely for reference purposes to help you remember the state of the snapshot. For example, a useful name would be “Fresh installation from scratch, no Guest Additions”, or “Service Pack 3 just installed”.

You can also add a longer text in the Description field. Your new snapshot will then appear in the snapshots list. Underneath your new snapshot, you will see an item called Current State , signifying that the current state of your VM is a variation based on the snapshot you took earlier. If you later take another snapshot, you will see that they are displayed in sequence, and that each subsequent snapshot is derived from an earlier one. Oracle VM VirtualBox imposes no limits on the number of snapshots you can take.

The only practical limitation is disk space on your host. Each snapshot stores the state of the virtual machine and thus occupies some disk space. Restore a snapshot. In the list of snapshots, right-click on any snapshot you have taken and select Restore. By restoring a snapshot, you go back or forward in time. The current state of the machine is lost, and the machine is restored to the exact state it was in when the snapshot was taken.

Restoring a snapshot will affect the virtual hard drives that are connected to your VM, as the entire state of the virtual hard drive will be reverted as well. This means also that all files that have been created since the snapshot and all other file changes will be lost. In order to prevent such data loss while still making use of the snapshot feature, it is possible to add a second hard drive in write-through mode using the VBoxManage interface and use it to store your data.

As write-through hard drives are not included in snapshots, they remain unaltered when a machine is reverted. To avoid losing the current state when restoring a snapshot, you can create a new snapshot before the restore operation. By restoring an earlier snapshot and taking more snapshots from there, it is even possible to create a kind of alternate reality and to switch between these different histories of the virtual machine.

This can result in a whole tree of virtual machine snapshots, as shown in the screenshot above. Delete a snapshot. This does not affect the state of the virtual machine, but only releases the files on disk that Oracle VM VirtualBox used to store the snapshot data, thus freeing disk space.

To delete a snapshot, right-click on the snapshot name in the snapshots tree and select Delete. Snapshots can be deleted even while a machine is running. Whereas taking and restoring snapshots are fairly quick operations, deleting a snapshot can take a considerable amount of time since large amounts of data may need to be copied between several disk image files.

Temporary disk files may also need large amounts of disk space while the operation is in progress. There are some situations which cannot be handled while a VM is running, and you will get an appropriate message that you need to perform this snapshot deletion when the VM is shut down. Think of a snapshot as a point in time that you have preserved. More formally, a snapshot consists of the following:.

The snapshot contains a complete copy of the VM settings, including the hardware configuration, so that when you restore a snapshot, the VM settings are restored as well. For example, if you changed the hard disk configuration or the VM’s system settings, that change is undone when you restore the snapshot.

The copy of the settings is stored in the machine configuration, an XML text file, and thus occupies very little space. The complete state of all the virtual disks attached to the machine is preserved. Going back to a snapshot means that all changes that had been made to the machine’s disks, file by file and bit by bit, will be undone as well. Files that were since created will disappear, files that were deleted will be restored, changes to files will be reverted.

Strictly speaking, this is only true for virtual hard disks in “normal” mode. You can configure disks to behave differently with snapshots, see Section 5. In technical terms, it is not the virtual disk itself that is restored when a snapshot is restored. Instead, when a snapshot is taken, Oracle VM VirtualBox creates differencing images which contain only the changes since the snapshot were taken. When the snapshot is restored, Oracle VM VirtualBox throws away that differencing image, thus going back to the previous state.

This is both faster and uses less disk space. For the details, which can be complex, see Section 5. Creating the differencing image as such does not occupy much space on the host disk initially, since the differencing image will initially be empty and grow dynamically later with each write operation to the disk.

The longer you use the machine after having created the snapshot, however, the more the differencing image will grow in size. If you took a snapshot while the machine was running, the memory state of the machine is also saved in the snapshot. This is in the same way that memory can be saved when you close a VM window. When you restore such a snapshot, execution resumes at exactly the point when the snapshot was taken.

The memory state file can be as large as the memory size of the VM and will therefore occupy considerable disk space. When you select a virtual machine from the list in the VirtualBox Manager window, you will see a summary of that machine’s settings on the right. Clicking on Settings displays a window, where you can configure many of the properties of the selected VM. But be careful when changing VM settings.

It is possible to change all VM settings after installing a guest OS, but certain changes might prevent a guest OS from functioning correctly if done after installation. This is because the Settings dialog enables you to change fundamental characteristics of the virtual machine that is created for your guest OS. For example, the guest OS may not perform well if half of its memory is taken away. As a result, if the Settings button is disabled, shut down the current VM first.

Oracle VM VirtualBox provides a wide range of parameters that can be changed for a virtual machine. The various settings that can be changed in the Settings window are described in detail in Chapter 3, Configuring Virtual Machines. Even more parameters are available when using the VBoxManage command line interface. Removing a VM. The confirmation dialog enables you to specify whether to only remove the VM from the list of machines or to remove the files associated with the VM.

Note that the Remove menu item is disabled while a VM is running. Moving a VM. Note that the Move menu item is disabled while a VM is running. You can create a full copy or a linked copy of an existing VM. May 17, Archived from the original on August 10, Retrieved July 6, Nano Server Blog.

We have our storefront servers load balanced. We have 2 delivery controllers. Any time I shut down one DC Citrix is inaccessible.

I see local host caching and SQL DB high availability, but nothing about how high availability for Storefront and Delivery Controllers should work or be configured. There are three classifications for on-premises releases: LTSR Long Term Service Release — these releases get 5 years of mainstream support from the release date, plus up to 5 more years of paid extended support CR Current Release — 6 months support from the release date.

Updated quarterly. This classification provides exceptions to the requirement that all components must be LTSR versions. To patch a Current Release, upgrade to the newest Current Release.

Current Releases are end-of-maintenance after 6 months, and end-of-life after 18 months. Be prepared to upgrade to a newer Current Release every 6 months.

Workspace app too. Cumulative Updates do not include new features. Current Release 7. Receiver 4. Or will you wait until the next LTSR, probably released sometime in ? Another option is to remain on LTSR with latest cumulative update until you see a Current Release with new features that are desirable enough to upgrade to. Or deploy Current Release in a separate environment. Some app vendors require you to remain on LTSR. Instead, always upgrade Citrix Licensing to the latest Current Release version.

Instead, always upgrade App Layering to the latest Current Release version. Once 18 months have elapsed, Citrix will not support it at all. Some components can be combined onto the same machine. Some components are completely standalone with no dependency on other components.

Some components communicate with other components, and thus are dependent on those other components. This enables multi-farm capabilities for the following components that are dependent on StoreFront: Federated Authentication Service can be used by multiple StoreFront servers. The profiles are usually tied to a VDA operating system version.

Citrix Licensing Server should always be the newest version. Citrix Studio should be the same version as the Delivery Controllers it is managing. Virtual Delivery Agents can be any version, including older or newer than the Delivery Controllers. See Director Feature compatibility matrix for details. The newest Workspace app along with the newest VDA supports the latest Teams optimization offload features.

LTSR versions of these components might not support the latest Teams optimization features. Component Upgrade Process In-place upgrades — 7. It is not necessary to install the base LTSR version first. For Current Releases, you can upgrade directly to the latest Current Release. Requires temporary sysadmin permission on SQL Server.

Not all components have databases. In-place upgrade the agents. Rebuilding of master images might be preferred, assuming you have time to automate it. If you need these older operating system versions, then install VDA 7. VDA 7. Windows R2 Start Menu is the same as Windows 8. Profile version — Newer OS means newer profile version. Older profile versions do not work on newer operating system versions.

This means that an OS upgrade results in new profiles for every user. Write a script to copy profile settings from the old profiles to the new profiles. See CTX Upgrade Windows 10 Version — In-place upgrade of Windows 10 versions is not recommended. For example, upgrading from Windows 10 to Windows 10 broke several features. Rebuild is cleaner. Considerations for upgrading the operating system version on component servers : Do not in-place upgrade the operating system version.

Instead, build new VMs, and join them to the existing infrastructure. New OS version requires newer component versions. That means you might have to in-place upgrade your existing component servers before you can add new component servers running a newer operating system version.

For example: Existing Delivery Controllers are version 7. You desire to migrate to new Windows Delivery Controllers. Only Delivery Controller 7. Upgrade the existing Delivery Controllers to 7. In-place upgrade the existing component servers to a version that supports the new OS. Check the System Requirements documentation for each component to verify OS version compatibility.

Build new machine s with desired OS version. On the new machines, install the same component version as the existing component servers. The new machines must be the same component version as the existing machines. Migrate load balancer, VDAs, Targets, etc. See below for detailed instructions for each component. Decommission old servers.

Upgrade Guidelines Test farms — Test Citrix infrastructure upgrades in separate test environments separate test farms : Due to forwards and backwards compatibility, VDA upgrades can usually be tested in production. Upgrade procedures for High Availability components e. The Test environment should look like production, which means HA too. Read the release notes, especially the known issues.

Have a rollback plan, including the databases. Check Subscription Advantage SA date on the installed licenses. In-place upgrade preparation : Make sure other admins are logged off before starting the upgrades. Close all consoles and PowerShell. Snapshot the machines. Current Release upgrades are cumulative. You can skip intermediary versions. Before upgrading anything else, upgrade the Citrix Licensing Server.

Install updated license files with non-expired Subscription Advantage dates. VDAs and Delivery Controllers can be different versions. If Zones , upgrade all Delivery Controllers in all zones at the same time. Director 7.

For Session Recording , the Session Recording server s must be upgraded before you upgrade the Session Recording agent. After upgrading, configure new functionality. Install the latest Current Release License Server. For 7. For XenApp 6. Prepare : run Smart Check, logoff other admins, close consoles. In-place upgrade one or half of the Delivery Controllers.

Upgrade the database when prompted. In-place upgrade the remaining Delivery Controllers. Run Smart Check again. Temporary sysadmin permissions can now be removed. To upgrade the operating system version of the Delivery Controllers: In-place upgrade the existing Delivery Controllers to a version that supports the new operating system version.

For Windows Server , upgrade Delivery Controller to version 7. For Windows Server , upgrade Delivery Controller to version or newer. Build one or more new virtual machines with the new operating system version. Install Delivery Controller software with the same version as the other Delivery Controllers. AutoDiscoveryAddresses to point to the new Delivery Controllers.

Remove the older Controllers as Secure Ticket Authorities. Decommission the old Delivery Controllers. From 4. Just click the link to start the upgrade. When the images are published , the drivers will be updated automatically by the ELM.
