Re: [Lxc-users] lxc.blkio.weight question
You have to run the tests on both containers at the same time, then you will see the difference. If no container need IO, your first container will get the same speed as your second.

[Lxc-users] why does lxc-checkconfig complain about CONFIG_UTS_NS=y ?
Hi folks, My kernel config file says "CONFIG_UTS_NS=y", and yet lxc-checkconfig complains User namespace: missing How comes? Version is 1.0.0 alpha1. Every helpful comment would be highly appreciated. Regards Harri -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.

Re: [Lxc-users] [Newbie] lxc container to container.
Hi. I think the best is the traditionally way between two machines: Connect via ssh and do what you want to. Its not a good idea in my eyes to break through the security isolation of containers because that could affect all of them. (something bad like getting root of lxc host and kill process) But maybe there is a way I didn't see. Regards, Andreas Am 17.10.2013 03:48, schrieb Vijay Viswanathan: Hi What is the best approach to communicate between containers? Basically, I need to be able to kill a process running in one container [ container-1 ] from another container [container-2]. Currently, Iam able to kill a process inside a container from the host but how can container-2 see stuff inside container-1 ? I understand container is for isolation but unfortunately, I have this scenario where container-2 need to be like a master container of container-1. Thx.
