Hello,

In qemu_command, vnc graphic device can’t be more than 1, as the following code show in qemuBuildCommandLineValidate():

If（sdl > 1 || vnc > 1 || spice > 1） {

virReportError(….);

return -1;

}

This check originally introduced by commit: 6fe9025eb.

Qemu: Error on unsupported graphics config

qemu can support multi-vnc-configuration in qemu process, but libvirt limit vnc graphics in only 1.

Is there any considerations in libvirt? can remove this restriction?
