SureBackup Job fails for VM using Hyper-V DDA

Post by nappe »

I have a Remote Desktop server that has a Graphics card assigned to it using Hyper-V Discrete Device Assignment. When I try to do a sandbox restore it fails since the host I'm using for SureBackup jobs fail does not have that graphics card.
The interesting thing is that I tested this using Microsoft Hyper-V Replica and it works fine doing a test fail-over of the VM on a host with no graphics card. So the same scenario works with MS Hyper-V replica but Fails with Veeam SureBackup

Is there any way I can work around this with Veeam so I don't get the error? I'm hoping the is a script or setting that I could run at the time of backup (or restore) so that the graphics card is removed before trying to boot the VM (i'm assuming the Remove-VMAssignableDevice device command won't work on restore since it is a different host and there wont be a valid location path).


Here is the error the sure backup job is showing:

Hi and welcome aboard,
Is there any way I can work around this with Veeam so I don't get the error? I'm hoping the is a script or setting that I could run at the time of backup (or restore) so that the graphics card is removed before trying to boot the VM (i'm assuming the Remove-VMAssignableDevice device command won't work on restore since it is a different host and there wont be a valid location path).
You can use a pre-job script that would remove of the video from the VM via PowerCLI, and a post-job script that would add it back. I don't know if the approach is a feasible solution for you. Another option is to try the same thing with pre-freeze and post-thaw scripts, but that's a bit more complex since the scripts will be executed in the Guest OS. Would be great if you could try that and let us know if it works for you. Meanwhile I'm trying to figure out if it is a bug or by design.

Thanks
