When I set a VM to 1G it's always unusable. Sometimes it's PackageKit that crashes first, which causes systemd-coredump to spin up and run out of memory next, and then oom killers start killing off various processes. Sometimes the oom killing just starts happening without a prior crash. In any case I never get a desktop.
With 1.5G RAM I usually get a desktop but then if anything crashes, and it seems like PackageKit is crashing often when under memory pressure (?), it kicks off systemd-coredump which makes the memory problem worse
systemd-coredump should probably short-circuit the coredump in oom conditions. I'm not sure what the exact conditions should be, maybe if the amount of free RAM is lower then the core size?
