Is it possible to support multiple instances_path?

Hello Everyone,

This is QingFeng from IBM, I have used openstack for years, now I did 
some investigation and noticed that instances_path in nova.conf in 
compute host can only specify one path to store the instances. The 
question is, is it possible to support multipath instances_path for 
different projects (tenants)?

For example, instances_path = path1, path2, and path1 for project1, 
path2 for project2, with this way, we can achieve the isolation and 
different storages of different purposes for different projects. This 
could be valuable in some situations.

So I am curious if there is any plan to do it so that I can leverage and 
don't have to implement it by myself. :-)

Thanks a lot!

Best regards

QingFeng Hao
