Not many people know that Novell actually now maintains a script to make XEN virtual machine cloning easy. It’s located in /etc/xen/scripts/xmclone.sh and part of the xen-tools package.
geeko:~ # rpm -qf /etc/xen/scripts/xmclone.sh
Try it out, I’m sure you will never waste your time with installing XEN virtual machines anymore.
The original script and the usage was also published here:
