Re: [libvirt] [PATCH] Move VirtualBox driver into libvirtd

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Change the build process & driver initialization so that the VirtualBox driver is built into libvirtd, instead of libvirt.so This change avoids the VirtualBox GPLv2-only license causing compatibility problems with libvirt.so which is under the GPLv2-or-later license. NB this change prevents use of the VirtualBox driver on the Windows platform, until such time as libvirtd can be made to work there. Signed-off-by: Daniel P.
