  • 1.  VMs with performance issues

    Posted Mar 06, 2016 10:07 AM

    We have a host with 16 CPUs with 2 VMs hosted on it (each VM has 8 CPUs). From time to time we have experience 100% CPU on one of the VMs yes the load on the host is normal.

    vmotioning the VMs to different hosts doesnt help.

    We've update bio/firmware & drivers for the host and ran hardware diag to confirm the hosts are OK.

    Is there anything else we can check?

    Do you see anything within the guest OS itself, e.g. processes in the Task Manager with high CPU load. You may also want to ensure that the VM doesn't run out of resources like guest memory, and starts swapping.
