Bug description:
Using the UCA ocata release of libvirt we sporatically recieve this
error message 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:

Warning **: reds.c:2463:reds_init_socket: reds_init_socket: binding

Please backport the fix for the following bug into UCA ocata/pike releases:
https://bugzilla.redhat.com/show_bug.cgi?id=1397440
The patch is documented here:
https://www.spinics.net/linux/fedora/libvir/msg144093.html
We've tested backporting this same fix using the ocata UCA libvirt
2.5.0-3ubuntu5~cloud0 source package and it fixes the problem for us.
