Solved CentOS 7 VM will not boot
-
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?

i copied that. now looking for the mariadb files
-
found the db files. now to figure out how to connect them
-
Oh database files, that sucks. What DB engine is it? MyISAM? InnoDB? Something else?

Wordpress database. running on centos7. so it is mariadb
-
MariaDB is an RDBMS. It isn't a DB engine. It uses other engines. MyISAM and InnoDB are the two most common. There is no MariaDB database engine option.

daerma.com is giving me some weird permission error too .i cannot install a plugin or theme, because it pops the FTP login info like my old install did. but I chown'd the wp directory to apache:apache. not sure what is up.
-
well i have been unable to recover everything correctly by copying from the drive that was originally attached.
Would it be possible to copy the boot partitions to the old drive and then try and attach it as the primary drive? That is more in depth CentOS than I know how to handle.
-
At this point I think i will just nuke and rebuild from scratch if I cannot copy the boot partition and have the system come back up. Going to be out all afternoon with the family so looking forward to any ideas you all come up with.
