Hi,

I'm evaluating lxc for use in virtualized routing/bridgeing
infrastructure. I'm particulary interested in conntrack and routecache
behaviour. I had run some tests and established that routecache and
conntrack is not shared between containers and base system. Are data
structures for routeche and conntrack in kernel shared (with each entry
marked with namespace id) or new data structure is created for each new
container?

Spare me RTFS. Thx

Regards,
Marek

Hi Eric,

>What does it matter?

It may affect memory consumption and performance in some unique setups.
Anyway I'm simply curious.

Regards,
Marek
