Bug Description

The order of routing table entries is not preserved after rebooting the network node. It causes the problem with dnsmasq when the virtual network is attached to a virtual router.

    Fixes order of route entries.

    Fixes bug 1083238

    This patch makes sure that a route entry for dnsmasq is placed first
    before any others (for example the l3-agent one). This makes DHCP work
    when network namespaces are disabled.

This is a blocking issue for configuration that do not use namespaces.

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!
