try doing it on dom0 as well.

The thing I'm not sure Debian is the "best" distro for people like
you, who like to use the distro's packages and would like it to "just
work". I'd actually recommend you simply use Centos5. Others on this
list have suggested Opensuse 11.3, but with updated kernel from
opensuse kotd. Or even Fedora 13, with third-party RPMs.

If you're willing to compile from source, you can use latest Xen and
pv_ops kernel. See http://wiki.xensource.com/xenwiki/Xen4.0 ,
tutorials section in particular.

Should be possible, regardles of what your dom0 distro is.
