Comment 5 for bug 1697729

[Impact]

 * libvirt sporadically throws the following error and can be seen in nova-compute.log:

2017-06-12 14:32:54.359 19007 ERROR nova.compute.manager [instance: d1af2a13-0a53-4d9c-ada3-683e4973f28a] libvirtError: internal error: process exited while connecting to monitor: ((null):63256): Spice-Warning **: reds.c:2463:reds_init_socket: reds_init_socket: binding socket to 10.141.112.21:5900 failed

 * This should be backported to improve the supportability of the SPICE console in OpenStack

[Test Case]

 * Create multiple instances with nova-compute (via horizon or openstack cli) using the spice-html5 console and watch your instances attempt to re-use already bound ports...

[Regression Potential]

 * Unknown regression potential but worth pointing out that this patch was used to fix this bug in the libvirt-3.1.0-1.el7 package release...

[Other Info]

 * We ran in to this bug as a result of the openstack ansible project using spice-html5 as the default console viewer in ocata (not sure when they switched from novnc to spice as default).
