Right, but how do you get all of the installer stuff to run in the
paravirtualised environment? :)

I'm not talking about a hardware-xen-vm-with-pvm-extensions, I'm
talking about paravirtualisation only. I'm sure one could -make- a
bootable single domu kernel image and sysinstall md with the
sysinstall being "xen aware" enough where needed.

In any case the initial step is still to get the xen DomU kernel
included in the current snapshot somehow; this can happen without
needing to look into the sysinstall stuff just yet.

One thing I really disliked with the CentOS Xen DomU installer is that
it really is only prepared for a -DOS- disk image, rather than being
given a set of partitions to initialise. I'd really like to avoid
being cornered into needing to do the same for FreeBSD DomU VMs
installed via sysinstall.
