Hello, If the running VM contains a floppy, creating snapshot fails internally, but the error is not detected by libvirt. Success is still reported to the user success, who will see the snapshots, even they are NOT created.
virsh # qemu-monitor-command --hmp winxp-1 savevm \"test\" Device 'drive-fdc0-0-0' is writable but does not support snapshots. virsh # snapshot-create-as winxp-1 test Domain snapshot test created Since there is no QMP command in qemu, libvirtd sends a HMP command to the running QEMU and parses the returned text. There only the following 4 strings are detected as errors: src/qemu/qemu_monitor_text.c:2822 # qemuMonitorTextCreateSnapshot() "Error while creating snapshot" "No block device can accept snapshots" "Could not open VM state file" "Error" + "while writing VM" Since none of them match the above message, libvirts thinks the command succeeded. libvirt-0.9.12 but also exists in git, QEMU 1.1.2 Tracked at <https://forge.univention.org/bugzilla/show_bug.cgi?id=30472> -- Philipp Hahn Open Source Software Engineer [email protected] Univention GmbH be open. fon: +49 421 22 232- 0 Mary-Somerville-Str.1 D-28359 Bremen fax: +49 421 22 232-99 http://www.univention.de/ -- libvir-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/libvir-list
