Hello. If I want to run any virtual machine (Fedora, Ubuntu,etc) with Virt-manager using Qemu/KVM as supervisor, it hangs. I've discovered it only happens if in host machine it's in use the official Nvidia (or the nouveau) driver (my machine is a Optimus system). But if I ban these drivers in boot time to force to use the Intel Graphical Device, virtual machines run flawessly. There must be some bug in Libvirt related to graphical display. Anyone has encountered an issue similar to this? Have you any clue? Thanks a lot

P.S: I'm using a brand new Fedora 29

Just and idea, have you change the libvirt load order so it load before your video kernel module, to see if still hangs.
