Bug Description

[ Impact ]
The autopkgtest for openvswitch on arm64 currently always fails, which prevents us from catching any real architecture specific regressions as dependencies are updated in the stable release.

[ Test Plan ]
Trigger autopkgtest runs against PPA and document their output / result.

[ Regression Potential ]
As this is a test-only change, I'd say none for the actual end user consumption of the package.

For CI stability however, the issue appears to have been present throughout the development phase of Noble, so there may be test cases with architecture specific flakiness which has yet to be uncovered. Rest assured, we will follow up with any required updates if they do appear.

[ Other Info ]
There is an issue with running the DPDK tests on arm64 which is currently worked around by using 1G hugepages as opposed to 2M hugepages (bug 2059400) as well as increasing the number of pages available (bug 2063112).

This workaround does however not work for the following tests:

    OVS-DPDK - MTU increase vport port
    OVS-DPDK - MTU decrease vport port
    OVS-DPDK - MTU upper bound vport port
    OVS-DPDK - user configured mempool

I propose we skip the test until we find a more permanent solution to this issue.

Hello Frode, or anyone else affected,

Accepted openvswitch into noble-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/openvswitch/3.3.0-1ubuntu2 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 on 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, what testing has been performed on the package and change the tag from verification-needed-noble to verification-done-noble. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-noble. In either case, without details of your testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.
