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 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, I use external snapshots to backup my guests. I use the 'quiesce' option to flush and frees the guest file system with the qemu guest agent. With the exeption of one guest, this procedure works fine. On the 'unwilling' guest, I get this error message: "ERROR 2016-05-25 00:51:19 | T25-bakVMSCmsrvVH2 | fout: internal error: unable to execute QEMU agent command

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 there! I will do soon the disk config, but first I will do some labs. I´m trying to install the virtio driver to comunicate using qemu-agent but when the driver is installed, the BSOD happens (win2k8 R2). I tried with virtio-drivers version 100, 110 and 117, both happens BSOD. Do you has a tip ? :) Thanks buddy! 2016-05-20 10:23 GMT-03:00 Dominique Ramaekers <

Hi Dominique, You’ll have to convert the qcow to raw, create a LVM-volume (don’t create a file system on the volume), and dd the raw tot he LVM volume… Convert the qcow to raw, Ok Create a LVM-Volume, OK Don´t create a file system on the volume ?? Is not clear why... DD the raw to the LVM? How ? I don´t understand this point.... Thanks a lot! 2016-05-20 10:23 GMT-03:00 Dominique

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 there! Although the guest has 2GB memory, the windows guest was adjusted to support this. I guess that the LVM is the best choice! I will save all images to other disk and re-build the partition with LVM. Do you recomend to use ext4 or zfs ? - About the apparmor, I have my doubts, I will try to disable and see what will happen! - About the tablet input device, I removed! Some forums say that
