Unfortunately, you're trying to work around misuse of the cloud API's, not

Slightly tangential to this discussion but specifically to your comment about
rebuild: HP (and I believe RAX) kept asking OpenStack infra to use rebuild in
node pool instead of constantly deleting and creating instances.
The reason being it would give them a significant performance advantage
and dramatically improve the use of resources in the operators cloud. Node
pool would have gained a vastly better resource utilization.
I didn't think that the overhead of deleting/creating an instance was *that*
much different than rebuilding an instance.
Do you have any information about where the "significant performance advantage"
was coming from?
