[virt-tools-list] [PATCH 0/7] [RFC] Install LXC guests with virt-install

[Cedric Bosdonnat]

Hello Lubomir,

This whole feature looks very similar to what Radostin and I worked on last year:

https://github.com/virt-manager/virt-bootstrap

You should really have a look at that tool: it allows you to create a libvirt-lxc
container out of a docker image, a tarball, or a virt-builder template. The good
thing is that virt-manager also uses it for setting up a local OS container.
