I have a 4 node hyper-v cluster running. All nodes are server 2012r2 and the cluster is present in scvmm (scvmm 2012r2).
The only issue I seem to have is actions that actions such as changing guest hardware, cluster refreshes and even guest shutdown take a long time.
Below is an example where I added 2 nic to a virtual guest, the whole process took 15 minutes. Is that normal? cluster refreshes have been known to take an hour and to shutdown a guest it is quicker to remote desktop and shutdown than issue the command from scvmm.
