Is there any way for me to identify which OpenVZ container I am in, from inside the container? I am working on a setup where OpenVZ machines shall boot the same (read-only) disk image, so I can not configure them individually in the file system. I need a unique identification for each of the virtual servers, to be used by scripts running inside the OpenVZ containers.
(I'm running Debian Lenny, BTW.)
Thank you for answer! HWaddr always looks loke this in the OpenVZ containers: "00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00". The unique identifier will be used to configure networking (and other init.d stuff prior networking is configured), so in my situation, IP address will not work neither. :( – Alfred Godoy – 2012-04-15T23:00:30.183
Another tought, the Hard drive is supposed to have a uuid field which should be different for each VM, but in any case you can get the IP first and then use that to personalize each container later. – jhcaiced – 2012-04-15T23:58:50.627
