Hello all,
I have configured a Hyper-V 2012 R2 Failover Cluster with two nodes. Firstly I should say that manual live migration working fine and all vm can be migrated to the other node without any interruption. Restarting any of nodes moving VMs to the other. No problem.
During my failover tests, I found difficult problem.
When I create a new HA VM (doesn't matter on which node) and disconnect cables from the node this VM is moved to the second one. Good! :) Normal behavior using "Protected Network". When I restore network connection I can manually move this vm without
any problem. The problem starts existing when I unplug cables and wait for failover the same machine next time. I get information: The operation did not complete on resource ... in detail information there is only "Cluster resource 'VM' in clustered role 'VMName' has received a critical state notification (EventID 1255). No auto failover. It still can be moved manually by clicking live migration.
When I delete VM from cluster role and bring as HA it can be failover again but only once.
Any advice ?
