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 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, currently i'm following https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit. I 'm playing around with it and it seems to be quite nice. What i want is a daily consistent backup of my image file of the guest. I have the idea of the following procedure: - Shutdown the guest (i can live with a downtime of a few minutes, it will happen in the night). And i think

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

Hi, I'm running into problems with blockcommit and gluster network disks - wanted to check how to pass path for network disks. How's the protocol and host parameters specified?

Hi, Recently We've upgraded some KVM hosts from Fedora 29 to Fedora 30 and now experience broken VM configurations on filesystem after virsh blockcommit. Commands "virsh dumpxml ..." and "virsh dumpxml --inactive ..." is showing diffrent configuration than the one on filesystem. In case of restart libvirtd or system reboot, there are broken VM xml configurations on

Hi, i have the following system: pc59093:~ # cat /etc/os-release NAME="SLES" VERSION="11.4" VERSION_ID="11.4" PRETTY_NAME="SUSE Linux Enterprise Server 11 SP4" ID="sles" ANSI_COLOR="0;32" CPE_NAME="cpe:/o:suse:sles:11:4" pc59093:~ # uname -a Linux pc59093 3.0.101-84-default #1 SMP Tue Oct 18 10:32:51 UTC 2016 (15251d6) x86_64

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

I have used virsh snapshot-create-as <VM name> <snapshot name> "<snapshot description>" --diskspec "vda,snapshot=external,file=/path/to/external-snapshot" --disk-only --atomic to create an external snapshot of a running VM. I followed it with virsh blockpull <VM name> --path /path/to/external-snapshot and monitored it until done.

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 have a strange situation: A domain is still running where domblklist points to a snapshot file and also dumpxml says the current drive is that snapshot file. But the file has been deleted hours ago. And the domain is still running. I can login via ssh, the database and the webserver are still running, domain is performant. How can that be ? Also lsof shows that the file is deleted:

Hi, i have a two node HA-Cluster with several domains as resources. Currently it's running in test mode. Some domains (all on the same host) stopped running, virsh list shows them as "paused". All stopped at the same time (11th of may, 7:00 am), my monitoring system began to yell. I don't have any clue why this happened. virsh domblkerror says for all the domains (5) "no
