[Bug 1976287] [NEW] casper: qemu image too small in autopkgtest

[Andrea Righi]

Public bug reported:

[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.
