Currently to make sysfs readonly, we remount the existing instance and then bind it readonly. Unfortunately this means sysfs is still showing device objects wrt the host OS namespace. We need it to reflect the container namespace, so we must mount a completely new instance of it. Do the same for selinuxfs since there is no benefit to bind mounting & this lets us simplify the code. * src/lxc/lxc_container.c: Mount fresh sysfs instance 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.
