when I use GNOME Boxes (with a Ubuntu 20.04 distribution) on my Fedora 33, my tabs on both Firefox and Chromium crash. I need to restart them, but after a few seconds it happens again. This problem only occurs when I use GNOME Boxes : just after closing Gnome machines, the problems disappear. It’s a really problematic bug for me .
I did not modified fedora execpt one thing : I enabled the scaling of the display.
Thanks in advance for everyone who could help me out !
You probably mean GNOME Boxes.
Anyway, the problem sounds like OOM.
Check the output when your machines are running:
Try to decrease memory allocation to the VM.
Sorry for the error (translation error), I corrected my initial post.
I get this kind of result:
total used free shared buff/cache available Mem: 7829 6245 163 593 1420 713 Swap: 3913 3198 715
So I think you are right, it is probably an OOM error
