Running a few windows vms on a single openstack computer (everything on one, for now). But they seem to behave badly... at least one of them and it's not always the same one.. It's on a "rather" powerfull server 2x6 cores (so total of 24 counting HT). And only 22 vCPUs are in use.. What happens is that the server freezes for a few seconds (up to ten) then starts working again for a few seconds.. then freezes again. What could it be?

The server with most problems is a 2vCPU windows 2012 r2-server. Maybe 2 vCPUs are to little? But this problem seems to have arisen after moving the images to a shared storage (NFS). But i'm not sure.. any insights?
