Package: openvswitch-switch Version: 2.3.0+git20140819 When systemd restarts the openvswitch-switch service, the running configuration (created via ganeti/xen, in my case) is wiped out, and all VMs lose their network connectivity.
This behavior only occurs when systemd restarts the service using the init.d script through the auto-generated unit file. If I add "_SYSTEMCTL_SKIP_REDIRECT=yes" to the top of the /etc/init.d/openvswitch-switch script and then call the init script manually, this behavior stops and everything is normal (i.e. All my VMs no longer lose network when restarted) This can also be avoided alternately by manually creating a proper /lib/systemd/system/openvswitch-switch.service unit file, which calls the following instead of the init script: ExecStart=/usr/share/openvswitch/scripts/ovs-ctl --system-id=random start ExecStop=/usr/share/openvswitch/scripts/ovs-ctl stop Either way, IMHO this is a rather severe bug, since the last openvswitch package upgrade called a restart which wiped out networking on my ganeti cluster due to this flaw. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
