There's also 3.8.0.27.27 from linux-generic-lts-raring. You're probably
using linux-generic-lts-quantal that comes from the install CD.
12.04 has many versions of supported kernels.

Short version? You can't. Not easily anyway.

Supporting multiple kernels is usually easier than supporting multiple
versions of userland programs on the same distro version, since with
kernels you won't have library linking issues. Plus the effort is easily
justified by the need to support newer hardware. With userland software
(e.g. lxc tools), the effort required usually outweights the benefits, so
you can't find it easily.

>From your questions, I assume you're not familiar with building packages
from source, or package pinning, so I'd say don't bother. Really. It's MUCH
more hassle than what it's worth. Either use the bundled lxc version, or
the daily ppa.

If you want a specific version anyway, and want it to be automatically
updated when you run "apt-get upgrade", you might be able to use raring's
version with pinning: https://help.ubuntu.com/community/PinningHowto . I
don't recommend this as this can EASILY break your system if you
misconfigure something.

Usually it's easier to just install lxc packages from raring (e.g. by
downloading from
http://packages.ubuntu.com/search?suite=raring-updates&searchon=names&keywords=lxc
)
manually, since you'd only need around four packages. If things go wrong,
uninstall only the new packages manually (e.g. dpkg -r --force-all), then
reinstall precise's version using apt-get.
