Ran into a simple one today to share. Wish I grabbed the screen shot today.
I noted my new install of SCVMM 2012 wouldn’t finish on my copy of Server 2008R2 Enterprise. It complained about being unable to launch Powershell and Failover clustering in the final window.
The answer? Duh! Make sure the Failover Clustering RSAT is installed on the SCVMM Server. I just went ahead and cheated and threw them all on.
Import-Module ServerManager; GET-WindowsFeature *RSAT* | Add-WindowsFeature; RESTART-COMPUTER
I reran the Install and I have SCVMM2012 running happily now.
