Afaik Xen in Ubuntu (and in Debian) is not very well tested..

support for Xen..
I would recommend you to use RHEL, CentOS, SLES, Opensuse or Fedora.. those
distributions are known to ship Xen and work to make it stable/usable..
Get for example Fedora 8, use it on both dom0 and on domU, and you should get
things working well..
I also have Fedora 8 as Dom0, but I think Ubuntu 7.10 runs less problematic Xen
than Fedora. I have numerous problems with Fedora 8, especially with
it's Virt-Manager and networking (doesn't support bridging out of the
box, have to do some tricks, virt-manager can't make a PV domain, doesn't have xenbr0 but virbr0 etc.
etc.). I just couldn't get used to it.
Nevertheless, my Pardus can't boot with its 2.6.21 xen kernel as I guess Fedora guys likes to make some non-standard way to making INIT. (Ubuntu kernels just boot fine on bare-metal).
I don't understand why I can't just replace the kernel and still boot fine (good old linux days?).
RHEL 5.1 or CentOS 5.1 should be good choises too..
Thanks a lot for your patience,
