LXC configuration issues on Ubuntu 18.04 (lxc 3.0.0) #16

Closed sgalgano closed 6 years ago

sgalgano commented 6 years ago

Reported on mailing list by Michael J. Vincent:

I've compiled the latest 1.2.2 and Protobuf 3.5.1; however, none of the EMANE tutorial simulations (https://github.com/adjacentlink/emane-tutorial) work. Investigating the issues why nothing starts - it seems LXC is at major version 3.x on Ubuntu 18.04 and that means config syntax changes (https://github.com/lxc/lxd/issues/4396#issuecomment-378322166).

I updated the scripts/demctl-init.sh script to accommodate; however, I'm still having issues - now with OLSRd not finding the /proc filesystem on the containers.

Steve, Thanks for opening the issue. Attached are the patch file for democtl-host that looks at LXC version and then use 2 new files for lxc2 and lxc3 templates to create the lxc.conf files.

The OLSRd finding /proc filesystem is fixed as well in the lxc3.template file in the ZIP patch above. Essentially need the command: lxc.mount.auto = cgroup:mixed proc:mixed sys:mixed

I'm going to stick with the modifications that were made in feature/issue16.

We have on our roadmap a revamped version of the tutorial that drops the use of makefiles and sed in favor of a template library. This will likely either use etce or an etce-like offshoot. We have largely been using Mako as our template language on other projects.

I've tested feature/issue16 modifications on CentOS 7, Fedora 27 and Ubuntu 18.04. The feature branch has now been merged into develop.
