We have a vmware cluster that has all Windows 7 VM's. I'm seeing a constant CPU load rolling between 50% to 90% every hour consistently. Any ideas what is going on with the VM's that could cause this? I was getting high CPU alerts on a couple of the hosts, but I increased the sensitivity of DRS and that has helped even things out a bit, but the first issue is still there. Please see attached screen shot from foglight.
