Hi everyone!

Would someone have some insight on how I can import a KVM image to Proxmox? I have a confluence server which I have in a KVM img format. I created a VM using qm create. I then copied the backup of the server I have to that servers hard drive in Proxmox. I booted the server using my KVM image and I got as far as the CentOS 7 loading screen but then the boot fails with an error message saying /dev/vda1 does not exist.

I thought, fine, no issue. I used GRML to mount the servers image.

On checking the fstab I saw the server was trying to boot from /dev/vda1 and /dev/vda2

On doing an fdisk -l I saw that the hard drives were/dev/sda1 and /dev/sda2 (http://prntscr.com/1273156)

I modified the fstab to reflect the /dev/sda1 and /dev/sda2 information above and I modified the grub conf to remove any reference of /dev/vda1 and replaced with /dev/sda1.

I reboot the server then this produces an error saying /dev/sda1 does not exist.

Next, I tried to put the UUID of the drive in the fstab but this also didn't work. I have now deleted the VM and recreated it but I am back to where I started. I still have a server that reports its drives are /dev/vda* (http://prntscr.com/1273l7e) But fdisk states they should be /dev/sda*

It's worth noting that I have tried to DD the image to the VMs hard drive and this produces the same results above.

How can I get this thing to boot?
 
I must have made a mistake the first time around. After redoing this, editing FSTAB and Grub it booted the first time with no need to touch initramfs. I did have to reset the root password as the old one wasn't working but seems to work fine now.

Thanks for the pointer
