[libvirt] [PATCH 4/6] Convert capabilities / domain_conf to use virArch
Daniel P. Berrange
berrange at redhat.com
Tue Dec 11 14:53:39 UTC 2012
From: "Daniel P. Berrange" <berrange at redhat.com>
Convert the host capabilities and domain config structs to
use the virArch datatype. Update the parsers and all drivers
to take account of datatype change
Signed-off-by: Daniel P. Berrange <berrange at redhat.com>
