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?
Yes, this restriction dates from the time QEMU was restricted to
1 display backend. We could certainly remove this restriction now.
