Thanks Daniel, after discussing shortly on IRC and checking all the references together: - https://www.redhat.com/archives/libvir-list/2017-September/msg00519.html - https://bugzilla.redhat.com/show_bug.cgi?id=1432684 - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=863266 - http://www.spinics.net/lists/netdev/msg454644.html
OTOH 4.13 is still iterating on Artful and should be the only >4.10 kernel available to Xenial eventually. Since there will be no valid 4.11-4.12 anywhere and in 4.13 this might actually break any other user of SO_REUSEPORT IMHO it should be fixed in the kernel to avoid all related regressions instead of tampering over it in libvirt. Therefore I'm bumping the Linux kernel bug task. Prio Crit as we are rather short to the Artful release, but obviously open to retriage by the kernel Team. ** Bug watch added: Red Hat Bugzilla #1432684 https://bugzilla.redhat.com/show_bug.cgi?id=1432684 ** Bug watch added: Debian Bug tracker #863266 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=863266 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1722702 Title: libvirt - vnc port selection regression with newer kernels Status in libvirt package in Ubuntu: Won't Fix Status in linux package in Ubuntu: Confirmed Bug 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1722702/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
