Maybe: from 6.3.0 release notes: - qemu: Fix domain restore from a block device When using namespaces, libvirt was unable to restore a domain from a block device because libvirt tried to relabel the device inside the namespace while QEMU was given FD to the block device in the host. cheers, t.

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

Hi guys, When performing live merge, in few cases, we see the following exception: Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 736, in wrapper return f(*a, **kw) File "/usr/share/vdsm/virt/vm.py", line 5278, in run self.tryPivot() File "/usr/share/vdsm/virt/vm.py", line 5247, in tryPivot ret =

Hi, Is it possible to "pivot" to a new image without doing blockcopy or blockpull? I know how to use snapshots and blockpull to create a new image and pivot to using it live, but what I would like to do is to have a VM switch from using imageA.qcow2 to image2.qcow2 while running. I don't see why this wouldn't be possible since some of the existing libvirt tools can do this when

Hi, a small update on this. We have migrated the virtualized host to use the virtio drivers and now the drive performance is improved so that we can see a constant transfer rate. Before it used to be the same rate but regularly dropped to a few bytes/sec for a few seconds and then was fast again. However we still observe that the following fails regularily: $ virsh snapshot-create-as --domain

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

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

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, 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 understand that libvirt provides async events that are triggered once the block job reaches ready state and successfully pivots as it is reported by qemu. Whats the event that is triggered and what's the handler that we have to implement? To be more specific, I am looking for the onEVENT callback method that is invoked when the event is fired.

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
