multipass build dies - possibly OOM killed

[Alan Pope 🍺🐧🐱 🦄]

Testing a build in multipass with:-

export SNAPCRAFT_BUILD_ENVIRONMENT=multipass
snapcraft cleanbuild

Killed
Failed to run 'override-build': Exit code was 137.
An error occurred when trying to execute "sh -c 'cd che; /snap/bin/snapcraft snap --output che_6.10.0_amd64.snap'" with 'multipass': returned exit code 2.

Here's the (simple) yaml to reproduce it if you're inclined.

I didn't get any kind of sentry option nor indication why it failed. I have run it again, and it looks like we have 1GB RAM and 4GB disk set aside for the VM. Is that enough I wonder?
