I am running Server 2008 R2 with Hyper-V. All virtual machines are stored on an iSCSI SAN. I have three host servers in a failover cluster.
Yesterday, one of my host machines failed and shut down unexpectedly. Failover occured as expected but the machines which were on that host were shut down uncleanly. One of them was a VM running Server 2012 which runs SCCM 2012.
I got the failed host machine back online and spread my VMs out over the 3 servers again. At this point I had not started my 2012 VM back up.
I tried to boot my server 2012 VM today and it has been stuck on a dark blue server 2012 screen with Please Wait and a spinning circle for 45 minutes at the time of writing this post.
I don't know what's happened to this machine - or why it is stuck. It was shut down cleanly yesterday when the failure occurred. Is there anything I can do to get this VM up and running again?
Edit:
It finally finished booting so I could log on. It took an hour and 6 minutes to get to the login screen. If anyone has any ideas why this might have taken so long (all other VMs are fine and boot quickly) and how to prevent it from happening in the future, I'm all ears!
It's now taking a while to actually login, mind you... stuck on applying user settings... so presumably there's still a problem somewhere.
