Using ... interesting question. I always assumed that virt-manager
starts a viewer, but I cannot find one in my process list. So: using
virt-manager.

My Arch system has "xf86-video-qxl" installed and loads the "qxl" kernel
module automatically when the guest configuration is set to using QXL.
It does not automatically load "bochs_drm" as mentioned here
(https://wiki.archlinux.org/index.php/QEMU#qxl). However, adding it
"manually" doesn't make any difference.

I know about Windows. I'm using these guests with QXL and the windows
drivers installed (AFAIK there are no virtio-vga drivers for Windows).
Contrary to Arch, Windows+QXL works satisfactory.
