The create snapshot API is this in upstream Nova:
There is no distinction between a live and cold snapshot in the end user
REST API. That's dependent on the backend compute driver. For example,
the libvirt driver may attempt to perform a live snapshot if possible,
but falls back to a cold snapshot if that's not possible. Other drivers
could do the same.
As for the difference between the OpenStack concept of a snapshot and
the VMware concept of a snapshot, I don't know what that is, but I can
saw we wouldn't add a VMware-specific REST API for snapshots to the
compute API when we already have the createImage API. So some design
work would be involved if you wanted to upstream this.
