...ommand emulation I had to update / patch up the existing SCSI disk support. This might be not to everyones taste, so I'm open to alternative suggestions. But I certainly do _not_ want to update the SCSI disk emulation, as this is really quite tied to the SCSI parallel interface used by the old lsi53c895a.c. Plus it doesn't do scatter-gather list handling, which is quite impossible to fix without proper documentation. Of course, if anyone else would step in here, I won't object :-) It currently runs guests with 2.6.27 and up; Windows XP support is not quite there yet. Anything else might w...

...model type error. I remove the usb controller entry from the xml, and add "-usb" as a "qemucommandline" parameter, but then libvirt adds the device lsi (-device lsi,id=scsi0 -usb), and the virsh create command fails with: "-device lsi,id=scsi0 No PCI bus found for lsi53c895a". The board we have created in QEMU does not have PCI bus implemented. Is there any way I can get my usb host controller to be recognized by libvirt? Is there a way I can prevent lsi device from getting added when I make -usb a qemu command line parameter? Regards, Deepti

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
