Instead of installing a new guest in Xen everytime, I have one default
image that is a bare install, kept up-to-date. When I want to provision
a new VM, I simply copy the disk image (file at the moment, evaluating
using a LV as a block device instead of tap:aio) then do a losetup,
kpartx, and change UUIDs of everything, mount the LVMs and ext3 boot
partition to change the hostname, IP, etc. of the system. When that is
done, I just do a `xm create new-system` after I've setup the config
file in /etc/xen and I have a system that is up-to-date and ready to be
used for what-ever purposes that have been determined (I've also thought
about installing new software while I'm chroot'd in the new guest
image).
