CentOS 7 VM will not boot
- 
 Ok, This VM was running along just fine this morning. I logged into SSH and told it to shut down with power off I made a change to the network card not part of the hyper-v switch, ran windows updates, and rebooted the windows server (Datacenter 2012R2, Core + GUI + Hyper-V) All of the windows server VM's booted up just fine. My CentOS 7 VM did not.

 Hope you made a backup!

 not yet I hadn't. was not too much on there, but enough that I am highly annoyed

 Looks like a corrupted or missing boot filesystem. Boot from a CentOS 7 Live CD to fix from there.

 the biggest thing on there was my daerma.com wordpress site. I do have a backup of that from the day I moved it to this VM. I will lose a few posts but nothing important.

 Getting the disc in is easy. Recovering May or may not be.

 cannot change the boot device. No idea WTF happened here.

 What hypervisor is that? If the firmware failed, maybe that is the issue.

 If the firmware failed, maybe that is the issue.Hyper-V Role inside Server 2012 R2. I did a quick Google and did not get any results. But I had to leave for a dinner with the family and friends. Will look again tonight.

 The Panic Code refers to a IPMI (BIOS) Issue. I wonder if you could just make a new VM and attach the disk to it and boot it?

 Not familiar with what might make HyperV do that

Created a complete VM installed CentOS and then shut down and added the old drive as a second HDD. it shows up when I check fdisk. So now to figure out how to copy the everything.

 looks like sdb3 is not readable? sdb1 and sdb2 mounted and were readable. Here is a screenshot. typo's included

 If you can see it like that, what is stopping you from just copying it?
