Actual, virt-install commmand line looks no less daunting to me. The Wiki described method should work for all RH derived distributions that are Xen PV compatible. I tried SME (or it might have been Trixbox... or both!) and it installed okay, but the kernel wasn't happy in a Xen world. Could fix it, but was lazy and used hardware virtualisation. Personally, I prefer to keep swap on a seperate partition, as it makes it easier to mount root. I don't know if that is possible under virt-install.

To be honest, I don't really think there are too many shortcuts with Xen, because it pays to understand how it works at a lower level, how to mount loopbacks, even with LVM's inside them, etc. I can't really remember the options under virt-install, but if they do 'dumb things down', then that may not be helpful in the long run. 

Anyway, both ways are way more friendly than debootstrapping your Debian system. ;o)

I think tap:aio is more favoured than file, for performance reasons.
