Today I’m going to write about a couple of major gotchas with LXC. Now these issues are documented in various places but I wanted to put all the relevant information together in one place to make it easier for people.
Before going any further it’s important to note that I created my LXC container with the official Ubuntu template from the latest “stable” LXC release i.e. I downloaded the tarball and put the template in the correct place as Ubuntu 10.04’s LXC package doesn’t contain said template. This helps minimise all sorts of problems especially ones related to the LXC console crashing and the like.
Firstly you will find when running “apt-get upgrade” (if you have Lucid updates enabled in /etc/apt/sources.list) that you get this error on upgrading udev:-
mknod: `/lib/udev/devices/ppp': Operation not permitted
