I am having some difficulty with migrations on our HyperV 2012 cluster. I have a 6 node cluster, with the below networks configured on each.
CSV - Cluster Communication - Physical NIC
Guest-Network _ Team - VM Communication
vm1 - Physical NIC
vm2 - Physical NIC
MGMT VLAN -Team - Management Communicaiton
MGMT 1 - Physical NIC
MGMT 2 - Physical NIC
RDP 1 - Physical NIC - Deployment - Not in use
RDP 2 - Physical NIC - Deployment - Not in use
vEthernet (Guest-Network) - HJyper V Virtual Adapter
On the "Failover CLuster Manager" everything is green ticked and happy - no errors reported.
However, In VMM 2012 its a different story. All the VM's are running fine, but all of a sudden I can do any migrations. This did work up until a few days ago and I do not know what has changed to make it stop working. When I attempt to do a migration between two hosts - the other hosts are greyed out and I get the error below.
"The Virtual Machine requires a virtual switch connection and the host network adapter is not attached to a virtual switch".
Again, I haven't changed anything on the networking side in some time. I would appreciate any ideas!
Many Thanks - Paul
