Hint, don’t upgrade you libvirt 1.2.12 to 1.2.16 yet. I use 1.2.16 with Qemu 2.2. and now I get a warning at the end of commiting the external
snapshot: warning : virEventPollUpdateTimeout:268 : Ignoring invalid update timer -1 All seems to go well so I won’t downgrade libvirt but it still worries me… I’m going to test Qemu 2.4 in Ubuntu 16.04 in march… Van: Keyur Bhalerao [mailto:keyurbhalerao@xxxxxxxxx]
Hi , Based on the discussion and links referred as mentioned in earlier thread , I could able to perform the block commit and other operations successfully. Here are the changes required to perform block commit 1. Used Ubuntu 15.04 which has following versions of Libvirt and Qemu Compiled against library: libvirt 1.2.12 Using library: libvirt 1.2.12 Using API: QEMU 1.2.12 Running hypervisor: QEMU 2.2.0 -- Need to mention here : The Qemu version 2.3 certainly has some issues regarding the block commit as lowering the version to 2.2 resolved "active block job" issue. 2. Modified the configuration /etc/libvirt/qemu.conf - Had to modify the qemu.conf file which is under /etc/libvirt to resolve the permission denied error. - Added security_driver="none" Supportive reference : https://libvirt.org/drvqemu.html I have two question regarding this.- 1. Is there any way we can avoid modifying /etc/libvirt/qemu.conf for security driver changes and perform block commit . ? 2. Has anyone tried with Qemu 2.4 for blockcommit and related operations ? Does it work ? (I know this might not be relevant to libvirt users for sure it will help if someone trying block commit and related operations) Thanks, Keyur Bhalerao On Tue, Dec 8, 2015 at 11:32 PM, Dominique Ramaekers <dominique.ramaekers@xxxxxxxxxx> wrote: 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. Van:

Namens Keyur Bhalerao Hi Was trying to get specific qemu-kvm version. Do you know any way to get the 2.1.2 installed. Was trying sudo apt-get install qemu-kvm=1.2.1 but its not working. Tried with sudo apt-get install qemu-kvm tree=1.2.1 But both have failed for Version not found.

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 security_driver="none". The result for this is no permission error but another error which
can be related to QEMU 2.3.0 virsh # blockcommit vm-01 vda --verbose --pivot --active Block Commit: [100 %]error: failed to pivot job for disk vda error: internal error: unable to execute QEMU command 'block-job-complete': The active block job for device 'drive-virtio-disk0' cannot be completed Searched more for this type of error and found - Looks like bug in QEMU 2.3.0 . Checking now with QEMU 2.1 for the same. Let me know if anything to more look for.
