Importing a instance from RBD backend

[Prashant Zanwar]

There needs to be ability, while moving between clouds, to import a instance into nova database, from X rbd pool, if RBD pool cloud can connect to.
Right now -

I am able to cp or snap/clone between two rbd pools, and or by doing "rbd mv src target" (within same pool). I keep cinder volume as placeholder by deleting rbd volume under that, and then with above method populate cinder volume back. And make it bootable.

Whereas I see, all this should be possible through API or CLI calls ..

I'm not sure how this relates directly to Sahara instead of, for example, Nova or Glance. Can you please elaborate more?

[Prashant Zanwar (pzanwar)]

It should relate to Nova, that's right. Not a Sahara bug .. Will I be able to transfer it to Nova ?

It can help, where direct upgrades from one version to other version are not possible, also when moving workloads between sites?
I am in a situation where I started with multiple clouds, and now I want to collapse and make one single cloud. I have network boundries and also 2 separate pools are used here between two physical locations.
