Ideally you would include LXC in your rootfs image via IMAGE_INSTALL
or similar but you are indicating in the way you are asking your
question that this is not the desired process for your circumstance.
Since you have network connectivity you can setup the resulting RPMs
in a package feed and then install the LXC package in the same way you
would do an 'apt install XXX' on a Ubuntu machine. This will pull in
all the required packages as well as LXC. LXC has a lot of
dependencies, you can examine them via 'rpm -qRp
tmp/deploy/rpm/core2_64/lxc-3.0.1-r0.core2_64.rpm'.
