58 device.  The gtk ui will start with a single window and each display
61 to its own window so you can see both display devices side-by-side.
63 For vnc some additional configuration on the command line is needed.
64 We'll create two vnc server instances, and bind the second one to the

68 	-display vnc=:2,id=secondary,display=video.2
70 Connecting to vnc display :1 gives you access to the first seat, and
71 likewise connecting to vnc display :2 shows the second seat.

126 QEMU version 2.4 and newer has a new pci-bridge-seat device which
127 can be used instead of pci-bridge.  Just swap the device name in the
