VMMS Hanging/crashing on 2008 r2 SP1 Hyper-V Cluster RRS feed

  • General discussion

  • I just wanted to put this out there in case someone else is having a similar issue.   

    I have two Dell R620 servers as two Hyper-V Cluster nodes.

    • Connected to Equalogic SAN
    • NIC Teaming enabled on Hyper-V Guest Network not shared with Host
    • Intel 10G 2P x520 Adapter
    • Intel Gigabit 4P x540/I350 rNDC
    • VMQ Enabled

    It seems there is an issue with VMQ being enabled, this was causing the VMMS service to hang/crash.

    The symptoms were that all of the VM's were accessable, but when an action such as rebooting/starting vm guests, they would get stuck in the starting or stoping state.   The only fix was to reboot the server, hard boot.

    Disabling VMQ has resolved this.

    I spoke with microsoft, they said its with the development team and they will be relasing a windows update to resolve this soon.

    When I get the KB number I will post it.
