Recommended display/GPU setup

2024-10-22 Thread Nils Kattenbeck 
Hi,

I have been looking around in docs, wikis and blogs which setup is
recommended to set up graphics for a local VM. So far I think the best
options are virtio-gpu/virgl and GTK display, or qxl+spice... Though some
docs also state that qxl+spice was primarily fast because it transmitted X
Server instructions which provides no benefits when using wayland or
kms/drm directly. Any advice would be appreciated.

Cheers, Nils

That could happen if you've got SELinux enabled. Try to put the .iso file 
into /var/lib/libvirt/images instead and then run a "restorecon" on the file.
