We have documents too, plus it's a learning experience creating the
configuration files (although we have a template with lots of helpful
comments so there's no mystery!).

Yeah, I've just booted my RHEL5.1 installation post kickstart and saw:

(XEN) PAE enabled, limit: 16GB

So that's good (-:

Ah, right. We don't allow DHCP on the server VLANs for security reasons.
Do you use more --extra-args= arguments for ip= netmask= and subnet=, etc.
or enclose the whole thing in speechmarks and use just the one?

Ah well, we choose to boot the box once first before we do stuff like that.
Our post installation configuration is... hairy to say the least so we like
to make sure the box is stable before we spend time updating it (-:

*blush* Confusion between activation key and installation key (-:

Maybe we'll be able to simply transpose the guests from the 32-bit host to a
64-bit. That would be nice.

Good enough! Thanks.
