Hi all,
I read the source code of Openstack Nova branch source codes but i
can not find the standard libvirt library packages, which i think
Nova uses libvirt
interfaces they are from standard libvirt library to attach Sheepdog(or others)
volumes to QEMU. If i add a new block storage driver for standard libvirt,
i have to update these libvirt library packages in Openstack Nova brahch.
Cloud anyone give me some suggestions? Thanks in advance ;-)

The nova driver for talking to libvirt is in nova/virt/libvirt/
The libvirt code itself is not part of openstack, and available from
our website http://libvirt.org

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.
Daniel, do you understand my meanings? Do you agree with me?

Of course, Libvirt and Openstack are two independent
and wonderful projects,
i love them very much ;-)

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.

Daniel

I think so, but i wonder if the standard "libvirt" python module is
nova/virt/libvirt/driver.py?
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.
But the libvirt python module is in the Nova branch. Why do you think it
is not a part of Nova? Is it part of libvirt code itself?

I think so, but i wonder if the standard "libvirt" python module is
nova/virt/libvirt/driver.py?
That isn't the libvirt python module. That is Nova's libvirt integration
driver code.

That is to say, libvirt.so is from standard libvirt code itself and libvirt
python module is from libvirt.so. They(libvirt.so and libvirt python module)
are part of libvirt. And Nova just uses libvirt integration driver codes.
But i wonder if they(libvirt integration codes and libvirt python module)
have any relationships? What and how do they have? Nova's libvirt integration
codes call libvirt python module, right?
