Ok, that'll be the problem. When libvirt prepends /.oldroot onto
the path, the symlink keeps pointing to /run instead of to
/.oldroot/run :-(

On Fedora "/var/run" is a relative symlink to "../run" to avoid
these kinds of problem.

As a quick workaround you can make your symlink relative too.

I'll get a fix into the next libvirt release to deal with
absolute symlinks better.
