Re: [libvirt] [PATCH 4/6] LXC: Wire up the virDomainCreate{XML}WithFiles methods

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Wire up the new virDomainCreate{XML}WithFiles methods in the LXC driver, so that FDs get passed down to the init process. The lxc_container code needs to do a little dance in order to renumber the file descriptors it receives into linear order, starting from STDERR_FILENO + 1. Signed-off-by: Daniel P.
