I'm running Windows Home Server as a Hyper-V guest. Yes, I know, its quite the odd setup...
What I'm seeing is that every week or 2, the WHS guest locks up, and when I try to reboot it from the Hyper-V console, nothing happens. I can't reset it, turn it off, shut it down - nothing works. My only solution when this happens is to reboot the host. I'm running a mix of other VM's on the host as well - all are either win2008 x64 or win2008 x86 - and I don't have this same problem with any of those guest machines.
Any suggestions as to where i should start in solving my problem? My first inclination is to reinstall the Hyper-V integration components in the WHS guest. After that, i'm not sure what to try.
