An old post, but still useful when cloning / imaging, so I tough I'd just post it here also.

Note: This should work with (open)SUSE 10 and later (as also other distro versions with slight modification).

A couple of months ago I came across a situation where I wanted to P2V a relay server from a small desktop to a VMWare ESX server. Making and restoring the image was no problem but after restoring and editing the relevant files, I thought I was on a roll until at boot up I got the message :
' waiting for /dev/sda3 to appear ...'.
Until now I had apparently been lucky enough to have a similar chipset when imaging from one system to another.

For those that might hit the same issue, here's my two cents for ya..
This can also be of use when swapping out vital components in your existing system.
