Thanks for your help ;-)
Actually i wanna let Openstack support HLFS, which is a sub-project of Cloudxy.
Our project web is: http://code.google.com/p/cloudxy/
HLFS's doc is: http://code.google.com/p/cloudxy/wiki/HlfsDesign .

And we will first realize Openstack support driver by QEMU/Libvirt way like
Sheepdog. Then we will also realize Openstack support driver by iSCSI. At
that time, if i happen to some questions, i will suerly ask you, would
you? ;-)
Do you understand sheepdog's driver by QEMU/Libvirt in details? If i add a
QEMU/Libvirt driver to let Openstack support HLFS, I should change following
stuffs, right?

1, add driver file to the dir (the same as sheepdog),
      https://github.com/openstack/cinder/blob/master/cinder/volume/drivers
2, change the file (Let libvirt attach HLFS volumes to QEMU, the same
as sheepdog)，
      https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py

Do you have any other suggestions?
