description |
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.
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 |
SRU Justification:

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. |
