Why not setup the hvm guests to use nfsroots with a brand spanking new
unpartitioned image as well? Just fdisk, format, copy over adjust
config / boot paramaters and reboot.
This also lets you work the neuances you'll need to address in udev and
others when converting. Well , may need to. I have no idea what you have
or I'd make more distro specific suggestions.
Just setup the nfs server on dom-0. I don't use HVM much, but I don't
see any reason why that wouldn't work.
Seems like the easiest way to go for me. Its quite easy to break up var/
usr/ and the rest doing it like that.
Hope this helps,
