Title:
  [arm64] autopkgtest - insufficient number of hugepages for all tests
  to succeed

Status in openvswitch package in Ubuntu:
  Fix Released
Status in openvswitch source package in Mantic:
  Confirmed
Status in openvswitch source package in Noble:
  Fix Committed

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 ]
  In bug 2059400 we switch to using 1G hugepages on arm64, as 2M hugepages does not work. For the OVN autopkgtests using 1 1G hugepage per NUNMA node is sufficient, but for the openvswitch autopkgtests that is not enough for all tests to succeed.

  Bump number of 1G hugepages for the openvswitch autopkgtest.
