At the moment Xensource is working on that, and the plan atm is to get pv_ops based dom0 patches ready for Linux 2.6.29. http://wiki.xensource.com/xenwiki/XenParavirtOps Latest pv_ops dom0 patches: http://xenbits.xen.org/paravirt_ops/patches.hg/ These patches have already been sent to lkml for review and comments.. Then again it will take a while to catch up with all the feature currently present in the Xenlinux 2.6.18 tree.. -- Pasi
