[Lxc-users] Can't start container with cgroup limits

2013-04-25 Thread Robin Monjo (appldiget)
Hello again, I'm facing a strange issue (a bug maybe ?) on ubuntu 12.04. Creating a simple container (lxc-create -t ubuntu -c cn0) and adding these lines in the config file: lxc.cgroup.memory.memsw.limit_in_bytes = 1G lxc.cgroup.memory.limit_in_bytes = 512M lxc.cgroup.cpu.shares = 512 results

Thanks great! But what I don't (yet) understand is shouldn't the new %P behaviour be the default of %p instead? I mean a container PID never makes sense in host user space since there is a 1:n mapping. Meaning PID x can have n mappings on the host. Thanks, Hans On 04/25/2013 12:23 PM, Stéphane

Re: [Lxc-users] Packet forwarding performance drop with 1000 containers

Hello, Working with 1000 containers I had already modified gc_thresh* to fit my needs. By mistake I had set gc_interval to a too high value (past 2^32) , forcing linux to set gc_interval to the default value (30) with is not suitable in my case. Setting gc_interval to 360 solved my problem.

2013-04-25 Thread Andrew Grigorev
What gc_thresh* values did you set?.. Having gc_interval=30 should not be a bad thing if you have a proper gc_thresh1 value. If you would disable garbage collector, as you did by setting large gc_interval, then your system could be accidentally DoS'ed by stopping/starting your containers, for e

I have 250 arp entries per containers and no more by design, so my values are : net.ipv4.neigh.default.gc_thresh1 = 28 net.ipv4.neigh.default.gc_thresh2 = 28 net.ipv4.neigh.default.gc_thresh3 = 28 In a real life environment, I would configure the value to have garbage collection work
