(you mean HVM) Please check the archives for pkg-xen-devel mailing list on alioth. Someone is working on packaging the necessary qemu-dm, I think there are packages available for testing too. > - PCI passthru to PV guests does not work, because > CONFIG_XEN_PCI_PASSTHROUGH is disabled in kernel config. I think this should be trivial to enable -- does any one on debian-kernel object to enabling it in trunk and sid branches? Note that this functionality is only in the xen flavours and not the pvops based regular flavours (-amd64 and -686-bigmem). > - USB passthru via PVUSB does not seem to work, because the required > PVUSB drivers are not available in the kernel. I don't think the PVUSB front or backends have been ported to the PVops kernel yet, most likely because nobody has asked for them. If you are interested I recommend raising it on the xen-devel mailing list, or better yet, sending patches to that list ;-).
