Maybe I'm missing something, and the semantics have just changed since multiple snapshot support? Anyway, rev 1.29 to block.c (http://cvs.savannah.gnu.org/viewcvs/qemu/block.c?r1=1.28&r2=1.29&root=qemu) switched to a path_combine and bdrv_open for backing_filename. This seems to currently lead to the behavior of: $ qemu -snapshot xpsp1.qcow2 qemu: could not open hard disk image 'xpsp1.qcow2' An strace shows: open("/tmp/xpsp1.qcow2", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory) Unfortunately I'm not comfortable enough to try to propose a fix... Thanks
