Yup, i think so. Therefore, i also think nova driver in nova/virt/libvirt
has some relationships with libvirt code itself, right? Nova driver
send parameters to libvirt client(in Nova branch), then libvirt client
send these parameters to libvirt serever(libvirt code itself). How do
they(libvirt client and libvirt server) communicate with each other
in details? I wonder if they(libvirt client and libvirt server) are a whole
one in libvirt code itself. And Openstack just call libvirt client interfaces,
which Openstack just package libvirt code itself to be a library for calling.
Nova simply uses the standard "libvirt" python module, which is a thin
python wrapper around the libvirt.so C library. This library talks to
the libvirtd server via a private RPC service. Nova only includes its
own custom libvirt integration code, the libvirt python module isn't
part of Nova.
