Open Stack

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 ;-)
