[libvirt] [PATCH 7/8] Enable driver modules in libvirt RPM



From: "Daniel P. Berrange" <berrange redhat com>

Turn on loadable modules for libvirtd. Add new sub-RPMs
libvirt-daemon-driver-XXX for each of the hypervisor
driver modules. Keep the secondary driver modules in the
main libvirt-daemon RPM, since there is no compelling
reason to install them individually. Adapt the existing
libvirt-daemon-XXXX RPMs to have deps on the appropriate
driver modules
