I found the topic below when looking to see if a problem/solution had been reported.
When installing and customizing the latest ISO, manjaro-xfce-21.3.0-220617-linux515.iso, in a Qemu virtual machine, I got an error, "module not found: ‘bochs_drm’.
The quick fix was to remove bochs_drm from mkinitcpio.conf.
But the topic, presented the question, should bochs_drm be removed.
Or, Manjaro should install the module, right now it’s half-complete and causes a failure.
