we are having the exact same issue with windows 2008r2 server vm on an all aio install on physical sata drives using virtio drives. was not a migration though, installed the vm and drivers from scratch and randoly every 24 to 48 hours the cpu usage maxes out. can only be fixed with a shutdown and start. thanks and regards, grant pasley. xtranet.

I forgot to mention that the vm have to be forcefully restarted when this happens.

When migrating servers using an iSCSI storage domain, about 75% of the time they will become unresponsive and stuck at 100% CPU after migration. This does not happen with direct LUNs, however.

What causes this? How do I stop it from happening?

Thanks
