Solved 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.

I'll have to google that process, but can do.

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.

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?

Was thinking to try that if my google fu fails later. Maybe I should just try it first.

Not familiar with what might make HyperV do that

Tried to make a new VM and just attach the VHDX with no luck.
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

learning more linux.. there is the data. so how to recover.

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