This is a clean install, so it's enabled by default and has reserved
4GB. I think that's what's actually causing the OOMs. I have 16GB of
RAM. On F32 I could run an 8GB VM with hugepages, i.e. dedicated
memory, plus normal stuff including multiple browser tabs etc. and
never had a problem. Now as soon as I try to start the VM it gets OOM
errors, and multiple Firefox tabs are failing and have to be restarted.
Oof!
One 8G VM , and how many FF tabs? What VM guest?
You can certainly experiment with a custom zram-generator.conf and xhange the limit to 16G. You'll get an 8G zram device in this case, if you make no other changes to the configuration.
I'm curious at what minimum zram allocation this problem doesn't happen. 6G, 8G, 10G?
