[Lxc-users] lxc-destroy does not destroy cgroup
Hi, Most of the time the lxc-destroy works properly, removing the cgroup with the same name as the container. Today something strange happened on one of my vservers - suddenly it stopped responding to requests and any attempt to connect just hanged (as if connection was successful, but no data was coming through). Checking dmesg on the host machine revealed that the vserver got into out-of-memory situation: *[304880.371274] Memory cgroup out of memory: Kill process 1959 (init) score 1 or sacrifice child [304880.403765] Killed process 10638 (apache2) total-vm:40608kB, anon-rss:12kB, file-rss:4088kB [304881.719832] bash invoked oom-killer: gfp_mask=0xd0, order=0, oom_adj=0, oom_score_adj=0 ...

IMHO it should be the last process to be killed, immediately after sshd, but that's a minor problem. When I tried to restart the vserver, it did not came up. Long story short, I found that lxc-destroy did not destroy the cgroup of the same name as the server. The cgroup remains visible in the /sys/fs/cgroup/cpu/master directory. The tasks file is empty though. I had to rename the container to be able to start it. All this on ubuntu 11.04, 3.0.0-12-server amd64.

If the bridge mac address changes then any OTHER nodes or routers on the network have to fail out their ARP caches and re-ARP for the new MAC address, resulting in the delay. The only way to work around this problem is to assign very high MAC addresses to the nodes on the bridge to keep them from changing the MAC address of the bridge itself. Setting the locally administered (0200 in first word) bit in the MAC address helps but may not be sufficient (warning - DO NOT set the MULTICAST bit (0100 in first word)!). This was a design decision made many years ago in the Linux kernel for reasons I did not agree with and do not agree with but it is what it is and I doubt it will ever change.

Re: [Lxc-users] How to start the network services so as to get the IP address using lxc-execute???
This isn't meant as an insult but you seem to be trying to do things backwards and expecting, worse, demanding, a low level tool to contain high level features that really should be provided by your own scripting, or by other tools that already exist for that purpose. If you want to assign container ip addresses in some particular order, then simply do so. You can ensure container IP's get set whatever way you want by any number of means. You can write a start script that writes IP's into the container config files and/or rewrites them dynamically every time it's started up, you can tell the containers to use dhcp and you can control the dhcp server. If you want to read the containers IP, you can get it from the hosts dhcp server state/log file or possibly from the arp table on the host or by directly reading files from the containers filesystem. Someone already gave you a good example of a simple bit of shell scripting that takes the container name and uses that to produce the ip address as long as the container names adhered to a consistent pattern. If that's not what you wanted then what? Chronological order? That's sort of meaningless since containers can be stopped and restarted. If you want the ip's to be assigned chronologically, ie, the first container to be started gets ip #1, that's trivial too, just write the start script to keep count in a temp file every time it is started, or have it parse the list of all running containers and add one to whatever is the current highest number running before starting a new container. But then this points out how meaningless this request is from the beginning. What happens after containers have been stopped and restarted? Do you want a restarted container to get a new next-highest number? or remember it's original number? If you want it to get a new number, then what happens when the always incrementing number gets to the end of the netmask? If you want it to remember the number that it got originally then what why not just write that number in it's config file from the beginning? If you want it to reuse IP's dynamically from a pool then that is already what a dhcp server does. I really don't understand what you are trying to do or trying to avoid doing or why, that isn't easily answered by a little shell scripting and/or a dhcp server. -- bkw On 12/8/2011 7:59 AM, nishant mungse wrote: Hi Greg, Thanks 4 reply.

Re: [Lxc-users] How to start the network services so as to get the IP address using lxc-execute???
Hi Geordy, You said that your script gets the IP from running container, but i dont want to use lxc-start I just want the IP address and use lxc-execute to start network services.
