[ovirt-users] Users Digest, Vol 47, Issue 70

[Grant Pasley]

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.
