Hi,
i experienced some strange problems when restarting a container.
Sometimes, it seems that the veth is not fully released on stop, then
the container failed to restart with the following log:
(in this case, the container have the same name of his veth.pair, but
doesn't matter)
lxc-start 1301749565.517 INFO lxc_start - 'cache2-crous' is
initialized
lxc-wait 1301749565.517 DEBUG lxc_cgroup - using cgroup
mounted at '/var/local/cgroup'
lxc-start 1301749565.517 ERROR lxc_conf - failed to create
cache2-crous-veth2vrehs : File exists
lxc-start 1301749565.517 ERROR lxc_conf - failed to create netdev
lxc-start 1301749565.517 ERROR lxc_start - failed to create
the network
lxc-start 1301749565.517 ERROR lxc_start - failed to spawn
'cache2-crous'
I can see the veth when i do an "ifconfig -a"
I can't destroy it with a "tunctl -d cache2-crous"
I can see it in /sys/devices/virtual/net/cache2-crous/
I must wait, 2 or 3 minutes, to have the possibility to restart the
container.
Here is the network config relevant to this container:
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = DMZ-CITE-U
lxc.network.name = eth0
lxc.network.mtu = 1500
lxc.network.hwaddr = de:ad:be:ed:03:01
lxc.network.veth.pair = cache2-crous
DMZ-CITE-U is bridge with a tagged interface attached to it (eth1.xx)
lxc is 0.73 package, kernel is a 2.6.37.2
it's related to the network namespace, and haven't test with a 2.6.38.
Is anybody seeing the same behaviour?
Can someone point me the right direction, to solve it?
Regards.
