Back to QXL video, which now works. Windows was very confused about how many screens it had - it was displaying on both, showing all menus and open windows only on the virt-manager window and also showing the desktop on the passthrough screen, but in the settings dialogue it insisted it could only detect one display, even though I could move the mouse cursor from one to the other. It seems to have settled down now, but I'm reluctant to touch anything for fear of breaking it again. poc _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
