[libvirt] mass create vm errors

[Vasiliy Tolstov]

Hi again =). I have another problem then testing libvirt with massive vm start:
2015-07-18 08:25:21.687+0000: 36893: error : qemuMonitorIO:750 :
internal error: early end of file from monitor: possible problem:
2015-07-18T08:25:21.586487Z qemu-system-x86_64: -vnc [::]:4,password:
Failed to start VNC server: Failed to bind socket: Address already in
use

As i understand, when libvirt try to detect free port for vnc it
fails, because another process already binds to it. How can i avoid
this errors? Does it fixed in never libvirt releases?

libvirt 1.216
qemu 2.4.0-rc0
