Re: [Lxc-users] Cluster Resource Agent
Hi Brian, I'm using the init script supplied with Ubuntu Natty. Regards, Christoph On 04/06/2011 07:55 PM, Brian K.

In theory there would be the VirtualDomain Resource Agent supporting libvirt. But since my libvirt experience together with LXC was not promising, I think the best option is to use lxc-tools. It worked for me when using the lxc init script (/etc/init.d/lxc) for active/passive configurations. As far as I found out only /etc/lxc/ and corresponding lxc rootfs dirs have to be shared. /var/lib/lxc should not be necessary, because lxc init script doesn't use lxc-create/lxc-destroy. Anything else to take care of when moving LXC containers around machines? For active/active and more advanced configurations an OCF Resource Agent for LXC would be nice. It could be similar to the ManageVE RA for OpenVZ: http://hg.linux-ha.org/agents/raw-file/tip/heartbeat/ManageVE Regards, Christoph What lxc init script? I think we all write our own and there is no official one yet. I write one for openSUSE but it's not in the suse lxc package nor in any other official suse package, just in a stand-alone rclxc package in my buildservice repo. If the official packages for other distros includes an init script, it will be different for each one since containers are such a low-level feature that can be used for so many different kinds of jobs, it's hard to imagine what an official init script would even be like. -- Xperia(TM) PLAY It's a major breakthrough.

This ability of creating an exogenous process inside a container requires a kernel patchset. C. -- Xperia(TM) PLAY It's a major breakthrough.

Nope, I created an opensuse container, so I know that works well but I didn't created the template. As far as I remember, it is very similar than the fedora container. Not really. I have a slightly out of date manual recipe here: http://en.opensuse.org/LXC opensuse has nothing like febootstrap which the fedora template relies on. The closest they have (without using an autoinst.xml) is zypper, but it still requires some user interaction no matter what. Much of the rest of the setup is different too. according to febootstrap developer and the thread with subject fedora template it is no longer usable in that way so i had created a different template using only yum so i beleive it could be done in the same way ith zypper i'll look into it I never made this into a template script because I hadn't yet decided if it was better to do this or do something based on an autoinst.xml instead. I follow this recipe myself when creating new containers if I'm not starting by copying a previously created container. It could be improved though. Some steps are unnecessary wrt the network config files in /etc, they just satisfy yast so the container looks more like a regular system to an admin who might use yast not realising he's even in a container. -- bkw -- Xperia(TM) PLAY It's a major breakthrough.
