template 'none' doesn't work with lxc-create

[Kevin O'Riordan]

Hi,

The man page lxc-create(1) says that with the '-t' option to specify a template '"none" can be used to force lxc-create to skip rootfs creation'. This does not appear to work.

root@somehost:/var/lib/lxc# lxc-create -n test.lol -t none
lxc_container: lxccontainer.c: get_template_path: 867 No such file or directory - bad template: none
lxc_container: lxccontainer.c: lxcapi_create: 1264 bad template: none
lxc_container: lxc_create.c: main: 271 Error creating container test.lol

There is no template in the templates dir corresponding to the 'none' template. I've looked through the upstream tarballs from releases 0.5.0, 0.6.0, ... , 1.0.0, 1.1.0, and there is no 'none' template in any. Might be just a documentation mistake, I guess. Could be a missing template, or maybe 'none' has a special meaning to the lxc-create binary; I haven't looked yet.

I'll dig a little further.

I'm using lxc 1.0.7-0ubuntu0.1 on Ubuntu 14.04 .

thanks,
Kevin

That stuff after my signature might be misleading. The host I'm working on, my desktop, is indeed running ubuntu 15.04, with lxc 1.1.2-0ubuntu3. The host I discovered the problem on is definitely running ubuntu 14.04 with lxc 1.0.7 .

Testing on my desktop, lxc-create fails but with a less verbose error message:

$ sudo lxc-create -n test.lol -t none
[sudo] password for user:
lxc_container: lxc_create.c: main: 274 Error creating container test.lol

I've had a look through the source code for lxc-create, and 'none' doesn't appear to have special meaning, so lxc-create probably looks for an lxc-none template in the template dir.

Works fine here both privileged and unprivileged, so looks like we fix this somehow in recent releases. I'll have this issue be closed with the 1.1.5 upload.
