Hyper-V Issue on DL380 G9 after SPP2021050 Install


Following the installation of SPP2021050 on a DL380 G9 Hyper-V host, I am unable to manage VMs on the host.

Issues include being unable to connect to VMs using Failover Cluster Manager and the Powershell command Get-VM fails.

Reported to HPE who confirmed it was not a hardware issue, which I knew, but as we only have hardware support this seems the end of the road for HPE support.

Issue is similar to but there are reported issues with this fix e.g. where the MOFCOMP command causes issues on the Hyper-V host where all boot items are removed from VMs and new VMs will not boot Re:

Advice from anyone who has experienced this and resolved it would be appreciated.

My proposed caouse of action at the moment is:

Force downgrade to previous SPP.

Run "mofcomp %SYSTEMROOT%\System32\WindowsVirtualization.V2.mof"

Remove and re-add the Hyper-V role.

One queston I would have is does the Hyper-V host need to be evicted from the failover cluster before removing and re-adding the Hyper-V role?

Any thoughts appreciated.

As I could not risk returning this server to production with unknown issues, caused by the installation of SPP2021050, I took the decision to rebuild the server.

I now have no confidence in installing any future HPE SPP and won't be doing it again in future.

I would suggest to log a  support case with HPE for further investigation including log analysis.
