check out xen-tools. It does not have a feature to copy a vm 3 times
with one call, but it can use image templates and adjust them,
probably it will also handle setting the hostname right.

It is made by a debian developer, mainly for debian, but it runs quite
nice on fedora and suse, too.

Not enough doc reading about Xen and it's architecture, and the config
parameters :)

xm doesn't change the settings inside of a guest.
The "name" setting in a VM config is NOT the dns hostname, and not the
/etc/hostname.
Often, one wants to have it like that, but this is not Xen's job.
