Administering High Availability for Hyper-V 51
4 From the Hyper-V Manager console, choose to Import the virtual machine
from the location it was exported to in Step 2.
NOTE: If the resource group of an HA VM is deleted prior to exporting the VM files
as recommended above, Hyper-V Manager will de-register the VM and the VM will
not be listed on the console even though the files are still available on the disk.
There is no mechanism to re-register the VM. In such a scenario, the only recovery
option is create a new virtual machine from the Hyper-V Manager console and
attach the VM to the existing VHD files or passthrough disks.
