Why Might HyperV HOST Configuration Version Be Set to 5.0 on Server 2016

As you can see in the screenshot below, my customers HyperV host (which is part of a two node cluster) is showing as only supporting HyperV version 5. Server 2016 should support version 8 HyperV Configuration.

Any thoughts on how to upgrade the HOST version would be appreciated, so I can upgrade the VM versions.

hyperv-ver

Thanks

    Hey,

    As mentioned, you might have your Cluster Functional Level version 8. You might have had your nodes upgraded from 2012R2 to 2016 without updating Cluster Functional level. You will need to upgrade to level 9. The following article covers cluster rolling update procedure: https://learn.microsoft.com/en-us/windows-server/failover-clustering/cluster-operating-system-rolling-upgrade
    Might also help: https://www.starwindsoftware.com/blog/cluster-rolling-upgrade-from-windows-server-2012-r2-to-windows-server-2016

    Cheers,
