per:
(remote-viewer:13074): GSpice-DEBUG: channel-display.c:1726 display-
2:0: received new monitors config from guest: n: 2/4
(remote-viewer:13074): GSpice-DEBUG: channel-display.c:1746 display-
2:0: monitor id: 0, surface id: 0, +0+0-1024x768
(remote-viewer:13074): GSpice-DEBUG: channel-display.c:1746 display-
2:0: monitor id: 1, surface id: 0, +0+0-1024x740

the guest requests to "mirror". Does it have enough memory for qxl? Do
you have `virsh dumpxml` ?
