Hi Scott,
I've actually been diving through those Nova code paths recently, to work on a
BP
to move the Nova libvirt driver to use libvirt storage pools for image backends,
so I may be able to help you. Just FYI, if my blueprint gets accepted, it may
actually reduce the amount of code that you have to write, since libvirt already
has a (limitted) storage driver for sheepdog (see the BP here:
https://review.openstack.org/#/c/86947/)
Best Regards,
Solly Ross

Subject: [openstack-dev] [nova] Looking for experienced guide to understand
libvirt driver
Hi folks!
I am working to add Sheepdog as a disk backend for the libvirt driver. I have a
blueprint started and an early version of the code. However I am having trouble
working my way thorough the code in the libvirt driver. The storage code
doesn't feel vary modular to start with and my changes only seem to make it
worse; e.g. adding more if blocks to 400 line functions.
Is there an experienced contributor that could spend 30 minutes walking through
parts of the code?
- Blueprint: https://review.openstack.org/#/c/82584/
- Nova code: https://review.openstack.org/#/c/74148/
- Devstack code: https://review.openstack.org/#/c/89434/
Thanks,
~ Scott
