Hi everyone! I use the libvirt(version: 1.2.2) and QEMU(version: 2.2.1) to test qemu snapshot features: I tried virsh blockcommit when VM offline, the virsh blockcommit failed: the error messase as below: error: Requested operation is not valid: domain is not running when I start the VM, the virsh blockcommit work fine! my question is：we need

Hi Kashyap Chamarthy: thank you very much for answer my question: 一： lead to VM filesystem becoming read-only 1： test case it lead to VM filesystem becoming read-only test case as follows: we want to snapshot for VM , to obtain VM incremental data，and use virsh blockcommit，qemu-img commit，qemu-img rebase to shorten snapshot chain. Details are as follows（when VM running state， we perform the

Hi , Working on the simple POC : Advanced snapshot using libvirt and qemu . Following are the exact steps which are followed . 1.

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

Thanks Kashyap for replying. QEMU has permissions to the directory which is having images. I will look into the AppArmor issue and find out more about this. Also as per suggestion from the link i have uncommented the user and group from the qemu.conf file - https://github.com/jedi4ever/veewee/issues/996 By checking more on the AppArmor and sVirt issue , i have modified the qemu.conf for

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? For a backing volume chain as below, executing virsh blockcommit fioo5 vmstore/912d9062-3881-479b-a6e5-7b074a252cb6/images/27b0cbcb-4dfd-4eeb-8ab0-8fda54a6d8a4/027a3b37-77d4-4fa9-8173-b1fedba1176c --base

This is not a libvirt/redhat question… With your method you can only revert to versions which are available in the standard repositories. You’ll have to download the packages manually to force a different version. Use with caution. There is a reason why the version isn’t in the standard repositories.

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

Hello one and all. Got a problem with libvirt 6.2.0 and qemu 5.0.0. virsh blockcommit mymachine vda --active --verbose --pivot works until it shows [100%] but it never actually pivots. It just sits there. Is this a known issue with 6.2.0 and i should try 6.3.0? For now i switched back to qemu 4.2.0 and this seems to solve the issue too. Any hints? Ahoi! t.

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

I had test the command virsh blockcommit, but it failed, with the libvirt version 1.1.0, and qemu version 1.6.0. Is this feature being developing?
