Public bug reported: 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 ** Affects: libvirt (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722702 Title: bind port regression To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1722702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
