Ofcourse. This change didn't go into tools/kvm/ since we only support the legacy 9p2000 protocol at the moment, which means that even though we can boot - it's quite unusable to work with. The trick is pretty simple: You need to name your virtio transport "/dev/root" (I think it's currently named "local" in qemu). Once it's named this way, boot with the following kernel cmdline added: "root=/dev/root rootflags=rw,trans=virtio,version=9p2000 rootfstype=9p rw" (You should be able to change version to one of the 9p2000 extensions). I've noticed that the transport *has* to be named "/dev/root", naming it something else (and adjusting the "root=" parameter) doesn't seem to work. Also, if it's named "/dev/root" I couldn't mount it as a simple filesystem from within a guest - not as root. -- Sasha. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
