Hi Zhang jia long,
What are the functions of libvirt.xml.template? Currently, we just
wanna to add a new
block driver(a new one as the same as sheepdog driver) to Openstack Cinder ;-)
The performances will be enhenced later.

Hi Openstack developers and Sheepdog developers,
I also have following questions, please give me some suggestions.
Thanks in advance ;-)
1, The libvirt codes in Nova branch are just interfaces which call the
standard Libvirt library, right?
(Or the libvirt codes in Nova branch are the standard Libvirt library.)
2, If i add a new block storage driver for Openstack by QEMU/Libvirt
way, should i also modify standard libvirt library and QEMU source
codes to let them support this new driver so that i can use this new
driver to let libvirt attach the new driver volumes to QEMU in Openstack?
3, Certainly, i should also do following stuffs.
a, Add a driver file to the dir in Openstack Cinder branch(the same as
sheepdog.py),
https://github.com/openstack/cinder/blob/master/cinder/volume/drivers
b, Change the file in Openstack Nova branch(Let libvirt attach
the new driver
volumes to QEMU, the same as sheepdog)，
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py
4, Should i have to do any other stuffs?

Thanks
Harry Wei
