This wiki page has some details about what's happening atm: http://wiki.xensource.com/xenwiki/XenParavirtOps ie. upstream (kernel.org) Linux 2.6.36 introduced addition of Xen PV-on-HVM drivers, Xen SWIOTLB, etc.. There's more stuff queued for 2.6.37, including initial dom0 support, and Xen pcifront driver, and optimizations to pv-on-hvm drivers. Jeremy (and others) can comment about the state of (new) git trees suitable for tracking. -- Pasi
