Comment 5 for bug 1009098

Looking again with a fresh mind it looks like the OSVW patch actually can be made to apply but the set of patches for the ATS feature I would rather not include as they seem to depend on some PCI config space rework from Xen-4.2.

Instead of just adding them to the current Xen version in Quantal, I actually merged against the latest Debian unstable version (which moves us from a pre-4.1.3 to a real 4.1.3 version). This would also have the benefit of several CVEs being fixed by that move. I gave the resulting build on amd64 a quick test of booting on my AMD test machine and starting a HVM guest via libvirt and a PVM guest via xm commands. The PVM guest I also saved and restored via xm. Hopefully that was enough to ensure no regressions were introduced.
