Comment 3 for bug 1877126

I can commission Bionic with 1GB of RAM, Focal fails. The Focal image is much bigger, 179M for Bionic AMD64 vs 346M for Focal AMD64. In Focal LXD is now isntalled as a Snap which requires more RAM. When I commissioned using Focal on a 4GB VM at idle the system was using 1244M of RAM, Bionic uses 677M of RAM at idle on the same VM.

AFAIK no one is tracking how much RAM Ubuntu images use. Netbooting does requires additional RAM as the entire OS image, kernel, and initrd must be stored in memory.

I agree MAAS should work with VMs that have 1GB of RAM. I'm not opposed to changing the default memory size but we should still allow 1GB for older versions of Ubuntu.
