I'm getting an error on a 2008R2 Hyper V host that has 2 guests. One server will start without any problems, but after this server restarts, the other guest will get stuck in a loop of starting...running...stopping.
I checked the event viewer and am getting the message 'New Virtual Machine' was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault. If the problem persists, contact Product Support. (Virtual machine ID xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
This server is a Dell T410.
I've researched this and saw that some people have had this problem with OMSA and BIOS on some Dell servers where the Power Management setting is changed to Maximum Performance and this resolves this particular problem for them. This however has not worked for me.
The only solution for me is to restore the OS vhd from backup from several days prior. This solution is obviously not ideal however.
This problem has happened 2x so far. I'm currently making a restore of the OS vhd for quick recovery next time but don't know what else could be the problem.
There are no reported errors with hardware on this server either.
