This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed- artful'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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. instance-000a6096.log:2017-10-09T01:42:16.017220Z qemu-system-x86_64: -vnc 0.0.0.0:0: Failed to start VNC server: Failed to listen on socket: Address already in use 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 Fix: Cherry picking a set of 3 patches (merged as the same set by David Miller) from upstream Linux. Testcase: Restart of libvirt. Risk for Regressions: Looking at the changes those 3 patches introduce, the delta is minimal and makes sense with respect to the explanations given in the commit message. Overall risk should be low.
