Sorry for the image of the screen, this error doesn’t appear to be logged in text anywhere.
I’m happy to blow away this VM and start again - I’m just not sure how I got into this situation - Xorg (I thought Wayland was default now?) doesn’t start and startx complains about a missing hyperv_drm_dri.so file. I can’t seem to locate this file via dnf whatprovides, either.
