Please upgrade to allow virsh blockcommit in Ubuntu 14. libvirt-1.2.9 (and above)

[ALU]

This is a feature request ticket.

Blockcommit makes snapshot/commit steps take fractions of a second instead of minutes. Perform efficient live disk backups using virsh blockcommit. This is possible with versions: QEMU 2.1 (and above), libvirt-1.2.9 (and above), but not any LTS version of Ubuntu.

Perhaps Trusty-Proposed?

I believe this feature is in the current 16.04 (xenial) version of libvirt. Can you ensure this works there first? Thanks

[ALU (c-launchpadmail)]

It works well in Ubuntu 15 and checking the package list for xenial shows ( http://packages.ubuntu.com/xenial/ )it has versions of qemu=2.5 and libvirt= 1.3.1 so it is a feature that is in 16.04 as well.

Not tested, but looks good.

There is still one bug 'bugging' me. I refer to https://bugs.launchpad.net/libvirt/+bug/1533728

If you run the procedure [create external snapshot] => [Active block commit] more than once, qemu won't allow you to create a new snapshot...

There is a patch released for Red Hat on Bugzilla.

If this could be processed on Xenial, that would be great!

Fix for that one is building in xenial-proposed as well.
