Xen hypervisor 4.0.0 released

Xen has released the Xen hypervisor 4.0.0. See the release notes for more information. "Xen 4.0 includes and builds the new pvops dom0 Linux 2.6.31.x kernel as a default. There's also long-term supported Linux 2.6.32.x based pvops dom0 kernel tree available. You can also use the old-style linux-2.6.18-xen as the dom0 kernel, or any of the various forward-ports of the 2.6.18 xen patches to newer kernels."

Xen seems to be somewhat quiet on their efforts to get dom0 support into mainline kernel.
Is it still planned for 2.6.35?

Was it ever planned for 2.6.35? Last I heard the patches were full of if(xen) blocks and had too much code duplication and deep manipulation (Linus called it "incestuous").

I think it's unlikely but maybe that's just because I hope it's unlikely! Only Linus knows for sure...

Well, at least Joanna Rutkowska still thinks Xen has a purpose and some advantages.
See:
http://qubes-os.org/
and esp.: http://qubes-os.org/files/doc/arch-spec-0.3.pdf

I tend to agree. KVM is good for most use cases, but it is not for every use case and competition is nearly always good.

BTW: Will our editor take a look at qubes?
