Hi I'm having an issue with the latest version of UNRAID 6.5, when I start my Windows 10 VM, one of the cores is pegged at 100%, but it's not Windows itself which is showing the usual 1-3% as normal but runs super super slow. If I shutdown and stop the VM the usage goes away, but I am unable to enter the VM Edit page, it just comes up blank. If I try to start it again I get various errors:

Timed out during operation: cannot acquire state change lock (held by remoteDispatchDomainGetBlockInfo)

Others too but I didn't copy them and now they aren't coming up ><

If I roll back to UNRAID 6.3.5 the issue goes away, but now I am stuck as I use unassigned devices and that no longer works with the old version.

Any help? Not sure what I need to attach for extra info.

 

Rolled back UNRAID, deleted VM (because it wasn't possible to delete in 6.5 as the pages wouldn't load), updated to 6.5, created new VM, still having the same issue, one core is pegged at 100% even though there is no actual load in the VM.

No additional plug ins, just UNRAID 6.5 itself.

Nevermind, not sure what happened but I just repeated the same steps a few more times this time leaving it on 1 core and 2GB RAM and it seems to have worked, so I edited it back to 3 cores and 4GB and it's still working.

Hi were you able to debug this any further? I've had this happen on a 4 core 8 thread server, trying to use core,thread: 1,5 - 2,6 - 3,7 for a gaming VM only to crash and lock thread 1 at 100% when running PC mark every time.

 

Removing core 1,5 seems to have fixed this, just wondered if you had any other thoughts on this.

Having this issue with a VM as well. It's an anomaly. Win10, 6 cores. The CPU usage reported is host only, in VM the CPUs are idle. So this is a hypervisor/VM configuration issue. I'm chasing it down as a libvirt/qemu issue since I'm not seeing a solution in the unraid searches. Check this thread out for example: link.
