I have a VM running under kvm (it is a .img file), the server it runs on crashed hard and restarted and finally got things up... I think I goofed and ran
yum install -y qemu-kvm
Which I am sure updated a ton of stuff on a very old unpdated os. I had issues after this machine died having it see vms were there like the KVM itself (the image files were there but they were not 'registered' anywhere). Not sure how I got that back but all the VMS did virsh start but one...it gives an error:
[root@sdss4-server1 ~]# virsh start sdss-host2
setlocale: No such file or directory
error: Failed to start domain sdss-host2
error: unsupported configuration: Only a single IDE controller is supported for this machine type
Did my file get corrupted? Can I repair it? I would LOVE to get this VM running again as there was no backup and some of the data needs to get off it. (I thought I could mount .img files in linux somehow? but I tried the following)
kpartx -av sdsshost2.img
add map loop0p1 (253:2): 0 208782 linear /dev/loop0 63
add map loop0p2 (253:3): 0 10490445 linear /dev/loop0 208845
device-mapper: resume ioctl on loop0p3 failed: Invalid argument
create/reload failed on loop0p3
add map loop0p3 (0:0): 0 62916711 linear /dev/loop0 10699290
[root@sdss4-server1 vm-cache]# sudo mount /dev/mapper/loop0p2 /mnt/host2
mount: unknown filesystem type 'swap'
[root@sdss4-server1 vm-cache]# sudo mount /dev/mapper/loop0p1 /mnt/host2
(I think this is a boot and the files in it are:)

Certainly not what I was looking for, it appears the loop0p3 is what I want to mount but the kpartx gives an error on that I do not understand fully.
So is my virtual drive/disk bad? Anything I can do to recover this some how?
