ÂI know that the Ubuntu 11.04 will be shipped with the Linux 2.6.38,
wich probably will come with the needed backend drivers!
ÂNow I'm working to test the Xen 4.0.1 compiled from sources but, used
with the default Ubuntu Kernel!
ÂI'll post the results here!
ÂBTW, 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!

This is interesting, as I thought that the Ubuntu folks were backing
KVM....

This has more to do with xen-compatible paravirt support being adopted
into the mainline kernel than it does with any Ubuntu policy, I
believe. KVM is in the kernel. The Xenlinux patches were proving too
administratively difficult to apply and support, from what I understand.
And since it's going into the kernel, all distros will have the option
to enable xen pv_ops in their kernels. Whether they support it with
frontend management tools is another issue....
