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

I have an automatic process setup. It's still pretty new and obviously in need of better error handling because now I find myself in a bad state. I run snapshot-create-as across all my vms, then do zfs replication to the target backup system, then blockcommit everything. virsh snapshot-create-as --domain $vm snap --diskspec $DISK,file=$VMPREFIX/"$vm"-snap.qcow2 --disk-only --atomic

Hello All, I think I have seen this in previous bugs. Trying to live backup qcow2 images. I am able to virsh snapshot-create-as and virsh domblklist shows correct new source, but I am unable to commit back changes to qcow base. I get the above error. Libvirt at 1.2.2-0ubuntu13.1.17 Qemu is (2.0.0+dfsg-2ubuntu1.22) I tried compiling latest libvirt, but cannot get it to connect to socket on

Dear Liam, You need to upgrade to the latest LTS version of Ubuntu (16.04). I refer to my message to this mailing list on 17/03/2016: Hi everybody, Following this user mailing list over a period of time, I saw a few messages regarding not being able using the external snapshot feature. I refer to this procedure: http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit I would

Hello all, I tried following this guide: https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit Unfortunately when I try to do the final virsh blockcommit step I always get the following error: error: internal error: unable to execute QEMU command 'block-commit': Could not reopen file: Permission denied I checked directory und image file permissions, app-armor profiles

Hi. I'm following here a conversation that was initiated on Kashyap's website [1]. We have a server we use as a host for virtual machines using KVM (virt-manager used for VM creation) and we would like to setup VM backups. Basically, we're thinking of a backup schedule like "keep 7 daily and 4 weekly backups". We'd rather not shutdown the VM every day so live backups

HI, I am receiving the following error when I try to run blockcommit: ============================================================== root@farnsworth:/var/lib/libvirt/images# virsh blockcommit pg94-test vda --top /var/lib/libvirt/images/pg94-test.snap4 --active --pivot --verbose error: unsupported flags (0x4) in function qemuDomainBlockCommit

hi, i am trying to blockcommit a external qcow2 snapshot back into its raw backing file like: sudo virsh blockcommit myDomainName vda --wait --verbose the output just shows: Block Commit: [100 %] and stays like that (i waited about an hour or so...). No "Commit complete" message. - explicitly passing --base and/or --top arguments makes no difference. - did not find a related log
