Happy new year folks,
we've got an openvz cluster with two nodes running debian 7.6 and
2.6.32-openvz-042stab092.3-amd64.
Networking of the containers is done via bridged vlan interfaces.
vlan-raw-device is a bond interface in mode 1 (failover) over eth0 and
eth1.
The interfaces where added in the containers via
vzctl set CTID --netif_add=eth0,,,,<bridge>
this triggers an unmodiefied /usr/sbin/vznetaddbr
When I try to live-migrate a container to the other node I run into
following error:
root@openvz1:~# vzmigrate -v -f=cpu -r no \
--live --keep-dst openvz2 651700
[...]

bridge on the source node:
root@openvz1:/etc/vz# brctl show br507
bridge name bridge id STP enabled interfaces
br507 8000.0018510e7494 yes veth651700.0
vlan507
bridge on the destination node:
root@openvz2:~# brctl show br507
bridge name bridge id STP enabled interfaces
br507 8000.002590f456cf yes vlan507
If you need further information let me know.
BTW: Live migration works on a secend cluster with the same configuration
without problems. The only difference is the kernel version:
2.6.32-openvz-042stab094.7-amd64
And I'm pretty sure that it was working last year and "I didn't do anything" ;)
Thanks in advance for any feedback.
Regards,
Nils
