Will the VM ids be always unique ? Would they be ever re-used ?
1) If I have terminated a VM and bring up a new VM, can the new VM get an Id which was used by an earlier VM which is now terminated ?
2) Will the Ids be unique across tenants & regions ?
Wikipedia says "While the probability that a UUID will be duplicated is not zero, it is so close to zero as to be negligible". Instance IDs, and IDs of most other objects in an OpenStack cloud, are UUIDs, so you can consider them unique across tenants, regions, and time, and perhaps even across clouds.
