Here's my configuration: Windows Server 2008 R2 Standard as a host OS, and two guests VMs running the same exact OS.
Yesterday, Trial Activation on all OSes has expired and quite naturally all machines shut down. I rearmed the host, but cannot log on to either guest VMs. From what I see, they start up normally (State is listed as Running) but CPU Usage seems to be stuck at 3% and when I connect to it all I see is black textmode screen with cursor blinking.
One of my VMs has several snapshots, and when I revert back, it starts up normally. Moreover, "reference VM" (the one I cloned these two VMs from) starts up just normally.
How can I troubleshoot this issue?

this sounds like a corrupt image.
if you are saying an old snapshot starts up fine while the new one is giving the black curser, there is a chance that during the license expiry shutdown, some changes on the image disk took place preventing it from booting again.
