On the qemu side everything is in git HEAD now, but I'm not sure about the qemu-0.11 release as I haven't really followed it. For the guest kernel the virtio cache flush support is now in mainline (past-2.6.31). For the host kernel side about 2/3 of the fixes are now in mainline (past-2.6.31) with the others hopefully getting in this merge window. >> Is it safe to recommend virtio to newbies already? > > I think so. I wouldn't. At least not for people caring about their data. It will take a while to promote the guest side fixes to all the interesting guests. IDE has the major advantage that cache flush support has been around in the guest driver for a long time so we only need to fix the host side which is a lot easier. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
