Upgraded to 5.4 and get error starting Win2008 server


Mar 23, 2010
The error in the task viewer is:
kvm: kernel doesn't allow setting HyperV VP_INDEX

Any thoughts on getting it started is appreciated. The old version was 5.2 and it booted fine in it.

Edit: Looks like if I can modify the kvm cpu options to add "-hv_vpindex" it might boot. Any ideas on how to edit that?

Edit 2: Manually running the task with "hv_vpindex" removed from the cpu options does let the VM start properly.

I tried qm set to set the cpu but cannot seem to get the options set correctly. I think that might solve my issue if I can figure out the syntax.
