I have an old IBM x3650 (7979) that I use for my dev lab running Server 2012 R2 Hyper-V role.
I have several VM's including Linux and they all were booting fine. I restarted the host server the other day and since then there is a single Server 2012 R2 guest that results in a :
Event ID 18560 : 'MED-WIN-V01' was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault. If the problem persists,contact Product Support.
I've seen a lot of posts relating to BIOS power options causing issues with running multiple VM's, like this
HERE but it doesn't seem to be the same issue. I have the power options mentioned already disabled and I'm able to run multiple VM's (including Linux machines).
It's just this one VM that refuses to start. Funny thing is they have all been running for a few months now with no issues, through restarts and all.
The VM itself is not particularly special, dual vCPU, dynamic RAM (same as the other VM's).
Can anyone offer any insight
