Yes. But have you enabled zram yet for swap?
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.
Check what's using the memory. zram doesn't *reserve* memory. It doesn't use any memory until you start swapping out. Try increasing the zram size. I would suggest at least 12GB. On my 12GB laptop, I have it set to 12GB.
Trying to get my head around that. You mean all of your RAM is potentially usable as compressed swap? How does that work? Surely it can never reach that limit?
