Justin Mammarella (jmamma) wrote : bind port regression

Bug appears in linux-image-4.11.x kernels on 16.04.3.
4.8.x and 4.10.x are okay.

When libvirtd is restarted on Kernel 4.11.0-x-generic or above , it loses all information regarding existing port bindings and is unable to correctly re-identify vnc ports that currently in use. libvirt attempts to bind to an existing port and fails.

Fairly certain this is the same bug reported, and patched in kernel-4.13.4-200.fc26 for Fedora https://bugzilla.redhat.com/show_bug.cgi?id=1432684
