Decided to take lxc for a spin as I never tried it before. Took a while to figure out how to use teh gentoo template. Eventually I made a script which illustrates the problems: lxc_name=lxc_test2 lxc_rootfs=/jocke/roofs #defaults to /rootfs, perhaps not the bets place #must create dir for rootfs and config or template BUGS mkdir -p "${lxc_rootfs}" #--path should default to this instead mkdir -p /etc/lxc/"${lxc_name}" #template suggested I added this echo 'lxc.network.type = veth' > /etc/lxc/"${lxc_name}"/config echo 'lxc.network.link = virbr0' >> /etc/lxc/"${lxc_name}"/config echo 'lxc.network.flags = up' >> /etc/lxc/"${lxc_name}"/config echo 'lxc.network.hwaddr = fe:11:22:33:44:55' >> /etc/lxc/"${lxc_name}"/config /usr/share/lxc/templates/lxc-gentoo --password=root --name="${lxc_name}" --path=/etc/lxc/"${lxc_name}" --rootfs="${lxc_rootfs}" ## After template has create lxc_test2 it says: #You could now use you container with: lxc-start -n lxc_test2 ## That should be: #You could now use you container with: lxc-start -n lxc_test2 -f /etc/lxc/"${lxc_name}"/config
Forgot one thing, if you dont supplay a --name , then the script errors out with a mysterious error msg instead of a nice err msg telling you --name is mandatory
1) Please post your `emerge --info' output in a comment. 2) Please explain the steps you took exactly, by reproducing both the commands and their output in order of appearance, pointing out the precise issue along the way.

It did take quite a long time to figure out what to do since the error info from /usr/share/lxc/templates/lxc-gentoo is very terse. Now I am done, please forward this to the LXC maintainer.
Created attachment 380544 [details, diff] Quick fix to improve usability This is improves the template creation for me.
You can try the original lxc-gentoo template at https://github.com/globalcitizen/lxc-gentoo and join #gentoo-containers on freenode. By default, LXC expects all container to be in some default directory (/var/lxc/somethinsomething?) where --name can find them. LXC is notorious for cryptic and unhelpful error messages and all this is worsened by the fact that all LXC developers I know are ubuntu ones, thus support for Gentoo is lacking (though it usually works out of the box). But we are working on it.
I found out that one should use lxc-create -t gentoo instead of manually running lxc-gentoo. This will deal with a few shortcomings of this script. I do wonder who manages the gentoo template? I figured gentoo did but maybe upstream does? I can think of a few improvents I would like to add. Like creating a ppc container on am64, this works with a tweaks to the chroot invocation. See https://bugs.gentoo.org/show_bug.cgi?id=516454

Please open a bug to the lxc github issue tracker. https://github.com/lxc/lxc/issues As far as I understand there is nothing for us to do here right? And there is not a real bug so closing this as invalid
