Tired of “Unsupported Cluster Configuration” for some of your VMs?
Inspite of my refreshing the VMs having this error……….fingers crossed……..sometimes the error went away….sometimes did not. I was getting really frustrated. Here is how to fix it, once and for all: In Failover Cluster Manager, check the name of the VM….if it is something like – “SCVMM server_name Resources”… rename it to just server_name. Then refresh the VM inside SCVMM’s Virtual machine Manager. VIOLA! the VM would be back to normal.
