[libvirt] [BUG] Re: [2/6] loadvm: improve tests before bdrv_snapshot_goto()

Hello, Am Dienstag 03 August 2010 06:44:26 schrieb Kevin Wolf: This patch broke restoring not-running VMs using libvirt-0.8.7 with qemu-0.14: When the domain is not running while taking a snpshot, the sn.vm_state_size == 0: 2021 } else if (sn.vm_state_size == 0) { (gdb) print sn $6 = {id_str = "1", '\0' <repeats 126 times>, name = "pre-update-flash", '\0' <repeats 239 times>, vm_state_size = 0, date_sec = 1302698007, date_nsec = 711909000, vm_clock_nsec = 0} ... Previously the qcow2 image was still reverted to the old state, so on the next start of the domain the qcow2 image would be in the state of the snapshot ... ... Now the qcow2 image is not reverted and when the domain is started, it is NOT in the state of the snapshot. I can't decide if this regression is an Qemu bug or libvirt should be adapted to this new behavior. I found the Bug also reported with Ubuntu and created a Bug in our own German bugtracker: <https://bugs.launchpad.net/qemu/+bug/726619> <https://forge.univention.org/bugzilla/show_bug.cgi?id=22221> Sincerely Philipp Hahn -- Philipp Hahn Open Source Software Engineer hahn(a)univention.de Univention GmbH Linux for Your Business fon: +49 421 22 232- 0 Mary-Somerville-Str.1 D-28359 Bremen fax: +49 421 22 232-99 http://www.univention.de/
