Comment 2 for bug 282858

This is not a bug, it is expected. A dom0 kernel is not included in 8.10 (intrepid). I would expect that the hardy dom0 should work, but haven't personally tested it. You could also consider the dom0 kernel from xen.org, debian, or opensuse.

Xen dom0 support on ubuntu should be back once xen dom0 support is in mainline Linux, this is expect in 2.6.28 or so.

Fedora is doing the same thing with dom0 support. opensuse and now debian unstable have recent forward-ported kernels.
