8.3. Running Red Hat Enterprise Linux as a Guest Virtual Machine on a Hyper-V Hypervisor
- Upgraded VMBUS protocols - VMBUS protocols have been upgraded to Windows 8 level. As part of this work, now VMBUS interrupts can be processed on all available virtual CPUs in the guest. Furthermore, the signaling protocol between the Red Hat Enterprise Linux guest virtual machine and the Windows host physical machine has been optimized.
- Synthetic frame buffer driver - Provides enhanced graphics performance and superior resolution for Red Hat Enterprise Linux desktop users.
- Live Virtual Machine Backup support - Provisions uninterrupted backup support for live Red Hat Enterprise Linux guest virtual machines.
- Dynamic expansion of fixed size Linux VHDs - Allows expansion of live mounted fixed size Red Hat Enterprise Linux VHDs.
parted). This is a known limit of Hyper-V. As a workaround, it is possible to manually restore the secondary GPT header after shrinking the GPT disk by using the expert menu in
ecommand. Furthermore, using the "expand" option in the Hyper-V manager also places the GPT secondary header in a location other than at the end of disk, but this can be moved with
parted. See the
partedman pages for more information on these commands.
