similar to: Blockcommit error

It seems that my version of libvirt does not support the flags that yours does either. I have the latest version from the Ubuntu repos and am running 14.04. What version are you running and do you know if these features depend on libvirt, or qemu-img to be upgraded? =============================================================================================

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.

Hi everyone!

Hi Eric, Thanks for the info. I see the value in this, but it isn't quite what I was looking for. Basically what I want to do is to switch between snapshots quickly. For instance, I am currently working on designing a HA SQL implementation with failover. So right now I have 5 VM's running postgresql as a replication group. I am trying a lot of different things and often have to take a

Hi, the implementation of xl cpupool-numa-split is broken. It basically deals with only one poolid, but there are two to consider: the one from the original root CPUpool, the other from the newly created one. On my machine the current output looks like: root@dosorca:/data/images# xl cpupool-numa-split libxl: error: libxl.c:2803:libxl_create_cpupool Could not create cpupool error on creating

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
