Hi, i have several domains running on a 2-node HA-cluster. Each night i create snapshots of the domains, after copying the consistent raw file to a CIFS server i blockcommit the changes into the raw files. That's running quite well. But recent the blockcommit didn't work for one domain: I create a logfile from the whole procedure:

Hi, i asked already a time ago about snapshots. I have some guests, each resides in a raw file, placed on an ext3 fs which is on top of a logical volume, for each guest a dedicated lv. The raw is not a "must have", if there are obvious reasons i can convert them to a qcow2. What i want is a consistent backup of each guest taken overnight. If possible i won't have downtime. I can use

Hi, i'd like to create snapshots of my running vm's. I have several hosts with SLES11 SP4 64bit. I use libvirt 1.2.5-7.1 . VM's are Windows 7, SLES, Ubuntu, Opensuse. I use raw files for the vm's. I try to orientate myself by http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit . The hosts are backuped every night by a network based backup solution (Legato). My

Hi, i'm cuurently a bit confused if a guest does have a valid snapshot or not. This is the xml: ... <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/crispor_1604/crispor_1604.sn'/> <backingStore type='file' index='1'> <format

Hi, i read that virsh uses internally qemu-img (http://serverfault.com/questions/692435/qemu-img-snapshot-on-live-vm). Is that true ? so snapshotting a running vm with virsh or qemu-img is the same ?

Hi! I was reading the Wiki about 'Live Disk Backup with Active Blockcommit, https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit and see that example shown seems to be using two different names for the same file. First showing the current block device in use: $ virsh domblklist vm1 Target Source ------------------------------------------------ vda

Hi, i can store the disk of a guest in a plain partition which isn't formatted. That's no problem, i did it already several times, although the promised speed increase didn't appear. But is it possible to create from such a guest a snapshot in a .sn file using virsh ? Regards, Bernd -- Bernd Lentes Systemadministration Institut für Entwicklungsgenetik Gebäude 35.34 - Raum
