hi Dwight, Sorry for the late reply. Probably you were right and there was something in the bash initial configuration/profile. It is deployed by puppet, that's why I missed it. After disabling puppet, I didn't experience this issue again. I need the check the bash configuration:) Thanks for the tip.

This is what I modified from the official lxc-fedora template: https://github.com/fajarnugraha/lxc/tree/centos-template Got it. Installed CentOS 56 quite nicely on my Fedora 19 system. I need to give it a close look over, particularly with regards to distro independent installation (IOW, installing say CentOS on OpenSuse, which was failing). This should go into the package, ASAP. In particular, it solves the problem of mismatched rpmdb version (i.e. when installing centos5 on latest ubuntu) by doing yum install twice. I accomplished that with an rpm --rebuilddb sortly after installing the minimal packages. This is good. Much appreciated. I'll look the actual code over in closer detail later. You said it was based on the official lxc-fedora template. That template has been changing (by me). What version of LXC where you working from? -- Fajar Regards, Mike -- Michael H.

I accomplished that with an rpm --rebuilddb sortly after installing the minimal packages. Unfortunatey using JUST that didn't work last time I tested installing Centos 5 from Ubuntu 12.04. So what I did was: - move rpmdb location to the correct place (Ubuntu put this in $HOME/.rpmdb) - try rpm --rebulddb - test with yum - if yum still complains, then reinstall a new environment using yum/rpm from the temporary environment. Relevant code section, https://github.com/fajarnugraha/lxc/blob/centos-template/templates/lxc-centos.in lines 195 - 230 You said it was based on the official lxc-fedora template.

It was a long time ago, I forked the branch from Serge's staging tree, with his last commit 60a742e0af on Jul 31, 2012. My change history should still be visible from the git commit log, so you could either try to merge it directly, squash it into a single commit, or write your own changes following the same principal above, as long as it works :) -- Fajar -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.

[Lxc-users] lxc-centos/lxc-rhel?
Hi, Recently I had to set up containers on centos and discovered that there is no template for centos/rhel in lxc-source. Googling turned up quite a few templates but I am not sure which one is preferred. I tried one which created the container alright but on starting the container, killed the host X and it didn't continue working afterwards i.e. it was stopped. The host OS is centos as well. Would there be a official centos/rhel template bundled with lxc? If not, which one is most preferred one? -- Regards Shridhar -- October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
