Issue
I’m in the process of moving VMs from a legacy Hyper-V cluster (Windows Server 2012 R2) to a new Hyper-V cluster (Windows Server 2016).
VMs can be migrated to the new Hyper-V cluster without any problems.
However, once VMs have been migrated, I am unable to move VMs between cluster nodes.
When attempting to move the VM in VMM (SCVMM 2016), host ratings fail with:
No available connection to the selected VM network can be found.
Ports are not available for VM subnet “.
If you proceed the following error is encountered:
No available connection to the selected VM network can be found.
Investigation
There are no destination host compatibility issues outside of VMM (verified with Compare-VM).
VMs can be moved successfully outside of VMM:
Move-VM “X500MAIL01V” -DestinationHostX500S2D02
If I disconnect the VMs Network Adapter I can move VMs in VMM.
Resolution
It was the VMM Cloud associations.
I’d associated the relevant Clouds with the new host group, but not the new logical network. Once the logical network associations were updated to include the new groupings, VMs could be moved without error.
