These release notes are for the Beta release of Microsoft's Hyper-V.
It describes usage considerations that apply to this release. It also describes the hardware and other requirements that apply to Hyper-V.
Usage considerations
The following are the usage considerations for this release.
- If you change the screen resolution while holding the mouse button down until the change is applied, all subsequent mouse clicks have no effect. To avoid this issue, release the mouse button before you apply a screen resolution change. To fix this issue, stop and restart the virtual machine.
- The use of Virtual Machine Connection within a Terminal Services session is not supported. This type of usage can result in unpredictable mouse behavior and keyboard behavior. To fix this behavior, close both Virtual Machine Connection and Remote Desktop Connection, and then run Virtual Machine Connection directly from the local computer. To avoid this behavior, do not run Virtual Machine Connection remotely.
- If you use Authorization Manager to manage access to a server running Hyper-V and the authorization store is located in Active Directory, removing a user from a role assignment that controls access to Hyper-V functionality has no effect because the user will still be able to access Hyper-V. To avoid this issue, use XML file as the store type. To fix this issue, use XML for the authorization store or delete the role to which the user was assigned.
- If you use Authorization Manager to manage access to a server running Hyper-V, be aware that all users who are authorized to view virtual machine output can view the screen thumbnail of a virtual machine in near-real-time without the knowledge of a user of that console. This is controlled by the Authorization Manager operation op_View_VM_Output and is configured for all members of the Administrators group by default. To avoid this issue, use Remote Desktop Connection to access the virtual machine. To fix this issue, configure that authorization so that only users who should be able to view sessions have the op_View_VM_Output operation capability.
- If you try to restart or reset a virtual machine when the physical computer is low on available memory, the virtual machine may be turned off instead of restarted. To avoid this issue, retain at least 512 MB of memory for use only on the physical computer. To fix this issue, you can try to start the virtual machine. If this does not work, you can modify the virtual machine settings to reduce the amount of memory assigned to the virtual machine.
- If you import or export a virtual machine in a saved state or with snapshots, the network settings will be misconfigured in the snapshots or saved states. When you try to restore the virtual machine from a saved state or snapshot, you will receive an error message that the virtual machine cannot be started because the network has been misconfigured. To avoid this issue, delete all snapshots and saved states before you export the virtual machine. To fix this issue, modify the virtual machine settings to reconnect the network adapter.
- Online backup of dynamic disks with spanned, mirrored, or stripped volumes is not supported. If you perform an online backup when a virtual machine has one or more dynamic disks with spanned, mirrored, or stripped volumes, or when both the virtual machine and the physical computer have dynamic disks, the backup will fail or the disk will show up as a foreign disk. To avoid this issue, place the virtual machine into a saved state and perform an offline backup. To fix the issue of the disk showing up as a foreign disk, use Disk Management to import the disk and then bring it online.
- If you connect to a virtual machine on which the integration services are not installed, the mouse is displayed as a dot in the guest operating system. To resolve this issue, install the integration services if they are available for the guest operating system you want to use. To avoid this issue, use a supported operating system and install the integration services for that operating system.
