Newer Xen supports this but it is in no way a requirement, the old way,
using plain filesystem images and kernel stored in the dom0 filesystem
also continues to work.

Pass your disk image as xvda and supply a kernel which support resierfs
using kernel = "..." and a command line containing root=/dev/xvda and
this should just work.

Or you can supply your disk image as xvda1 and use root=/dev/xvda1, it's
mostly up to you.
