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
There has not been much movement in that particular area since 1.2.16.
There's inherent race though: by the time that libvirt detects that a
certain port is free and qemu binds to it. During this window another
process may just allocate the port which will result in the error
message you're seeing.
One of the solutions may be to use static ports, or make sure that other
programs don't interfere with the range that's reserved for graphical
sessions (the range can be configured too in qemu.conf).
