Hello Adam, or anyone else affected,

Accepted libvirt into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/libvirt/1.2.2-0ubuntu13.1.9 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Hi Adam,

could you please give this package a test? I tried to test it, but I don't know which messages are the ones which were missing. (If you can just tel me what those are i'll test it)

Confirmed this fixes the issue:

Current version shows the following apparmor errors when spinning up a virtual machine with '-device sga', and the console log does not contain any early boot stuff:

Upgrading to 1.2.2-0ubuntu13.1.9, after spawning a machine there DENIED errors dont show up and my console logs contain early boot stuff:
