 I know that the Ubuntu 11.04 will be shipped with the Linux 2.6.38, wich
probably will come with the needed backend drivers!

 Now I'm working to test the Xen 4.0.1 compiled from sources but, used with
the default Ubuntu Kernel!

 I'll post the results here!

 BTW, I'm working on a new Xen 4 Ubuntu Packages, that will include all Xen
stuff, like blktap2, netchannel2, HVM and stubdomains, etc... Because the
Ubuntu does not provide the latest Xen version...

Cheers!
Thiago

Have you ever considered working with the Debian pkg-xen team?
I don't think one more brain would hurt. And by the way, we have
already xen-qemu-dm (eg: HVM support, which I maintain) ready,
and Waldi (eg: Bastian Blank) did quite a huge work on packaging
Xen for Debian. It would be silly to do the work twice when we are
in fact lacking resources.

I wouldn't get *too* excited - it isn't actually possible to compile
without DOM0 if you configure a Xen kernel along with PC platform
support (ACPI/APIC/PCI/etc).

But its a good preview of what to expect going on as Dom0 support just
becomes an expected part of the base kernel.
