During startup, the LXC driver uses paths such as /.oldroot/var/run/libvirt/lxc/... to access directories from the previous root filesystem after doing a pivot_root(). Unfortunately if /var/run is an absolute symlink to /run, instead of a relative symlink to ../run, these paths break. At least one Linux distro is known to use an absolute symlink for /var/run, so workaround this, by resolving all symlinks before doing the pivot_root(). Signed-off-by: Daniel P.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
