Hi, in my test lab environment I created Windows 2012 R2 Failover Cluster with 4 Servers to get Hyper-V HA.
I had no issues with Windows 2008 R2 or Windows 2012 before in same setup (2 NIC, FC HBA, SAN storage), but this time I cannot creat VM using Failover Cluster console:
Roles - Vurtual Machines - New Virtual Machine - Select Host -> <ANY HOST>
I'm using default settings during VM creation (except setting path to VM manually to pont to desired disk).
IN progress I see disk creation and both VM configuration and .vhdx files on target disk, but after that I see "The Operation has failed. An error occured creating a New Virtual Machine. Invalid Class.
In fact I see virtual machine in Hyper-V Manager and it's fully functional, but not added to Failover Cluster Roles. When I use Configure Role - Virtual Machine to see eligible machines - it's not there.
Cluster Validation says that everything is OK.
I wasn't able to find anything in Eventllog(s) or %SYSTEMROOT%\Cluster as it was in Win2k8.
How should I troubleshoot this issue ?
