Subject: red-qxl: Make sure we have at least one monitor
|
|
|
|
It does not make sense to have a graphic card without a monitor.
|
|
In spice_qxl_set_max_monitors we prevent to set 0 monitors, do
|
|
the same in spice_qxl_set_device_info.
|
|
|
|
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=1691721.
