So wait -- what happens now if you try to attach a disk with a qdisk backend to a PV guest that didn't start with qemu running? I'd really like to see patch 3 get in, but I'm not really in favor of this sort of a user-visible hack, particularly as we have to support it in libxl more or less indefinitely. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
