Bug description:
  [Impact]

  During autopkgtest we are creating VMs with 768MB of RAM, that used to
  be enough in the past, but nowdays we typically require more memory
  and we may trigger some sporadic out-of-memory failures during
  autopkgtest.

  [Test case]

  Run autopkgtest with a recent kernel (e.g., 5.15 or above).

  [Fix]

  Bump up the memory size to 1G.

  [Regression potential]

  We may see regressions in test systems with a small amount of memory
  (in the host / hypervisor), because after this change we need more RAM
  in order to run and complete autopkgtest successfully.
