Bug Description

The current implementation makes use of the libvirt type=ethernet. This is problematic in a number of respects. The driver should make use of the type bridge.

    Part of the patch set that enables VM's to use libvirts bridge type.

    Fixes bug 1078210

    The bridge will be created by Nova and not by the agent. This is the first
    part for the blueprint vif-plugin-improvements

    This patch supports Nova managing bridges too.

    In addition to this it cleans gateway code no longer used.

    Part of the patch set that enables VM's to use libvirts bridge type.

    Fixes bug 1078210

    The patch set enables the following:
    1. Bridges to be created by Nova
    2. Bridges to be created by the agent

    The code is backward compatible, that is, if Nova does not create the brdige
    then the agent will create the bridge.

    In addition to this it cleans gateway code no longer used.

    The patch enables the following Nova code to be backported:

Hello Gary, or anyone else affected,

Accepted quantum into quantal-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/quantum/2012.2.1-0ubuntu1 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!
