Just as you would any other server. The Xen config file simply populates
the guest with its drives, ram, kernel, network interfaces. When that
guest boots, treat it like you would any regular computer.
You will need to (at the minimum) setup :
/etc/fstab (so it matches the drives you gave the guest in the config
file, rootfs and swap at the least).
/etc/sysconfig/network-scripts/ifcfg-eth0 (if you want networking),
or /etc/network/interfaces if using a GNU (Debian-ish or Debian) distro,
/etc/passwd | shadow (if you want to set the root pass prior to booting
/etc/resolv.conf (just throw 4.2.2.2 and 4.2.2.3 in there, or use the
resolvers your data center / ISP gave you)
/etc/hosts (the VM should know about itself and localhost at the least,
if using NFS you'll probably want more)
/etc/hostname (depending on your distro)

Just remember, once you assign a VM drives and nics, the VM has to be
told how to use them. Likewise, whatever OS you're using has to be
configured to the point that its usable.
Part of the beauty and simplicity of Xen is guest OS's (even PV), for
all intensive purposes appear to be just a regular computer. So in
short, whatever you'd setup on a regular computer using the OS you're
virtualizing, you must setup in a dom-u.
