I think it still needs a new transport. > Hi, Mukesh Rathor > > Does pvh guest support virtio devices? > Currently there are three transports available: virtio over pci, virtio over mmio and virtio over channel I/O. They all seem to require some sort of emulation support. PVH doesn't have emulation support, which means you can't use existing virtio transports. If you want to add emulation to PVH, in effect it's just a HVM guest. You can already use virtio over pci emulation on HVM guest today. BTW can I ask why you want virtio support?
