Re: [libvirt] [PATCH 22/23] Add a virtlockd client as a lock driver impl

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; This adds a 'lockd' lock driver which is just a client which talks to the lockd daemon to perform all locking. This will be the default lock driver for any hypervisor which needs one. * src/Makefile.am: Add lockd.so plugin * src/locking/lock_driver_lockd.c: Lockd driver impl Signed-off-by: Daniel P.
