New Hyper-V host that's been running smoothly since deployment 1st week of January. It has 3 guests. The ones running fine are a P2V W2K3 box and a backup DC. The Exchange guest is giving me problems.
The Exchange 2010 guest started running with very high CPU utilization (the host never reported over 11% but in the guest OS it was maxed out most of the time, usually from task manager) sometime this morning near as I can tell. It was unresponsive via OWA, MMCs would crash so I couldn't bring up an event viewer. I tried to remotely view event logs but I got a network timeout.
Rebooted but several exchange services timed out and won't start. Safe mode booted up fine but I can't find the cause for the latency. I ran procexplorer to make sure the signatures were legit and they seem fine.
I suspected transaction logs but the disk is far from full (only about 10 GB in use out of 360). I did notice that the Exchange backups had been failing (the destination network share went away) and transaction logs go back to 1/27. There's about 8000 of them.
I did start a backup pointed to a valid destination but due to the latency it's moving at a snail's pace, it later timed out waiting for a VSS backup. I'm not sold that it's the transaction files, but I am at a point where I'm not sure what to do with that.
Watching the guest's heartbeat it occasionally goes to "Lost Communication" for about 15 seconds or so then switches back to OK for 5-10 secs and then repeats.
Even in safe mode, the guest runs impossibly slow.
The VM host is running very smoothly, no errors or latency. I'm completely befuddled.
Thanks in advance for any help you can offer me!
