... or boot a hdd-less xen system via pxe and mount a remote blockdevice (san) 
in the initrrd and use it as root device. this definitly works but also 
requires some work to be done to set something like this up. espacially the 
initrd part where network support & san support must be included and 
scripted. so the difficult part is not the xen related part at all...
