Is it possible to launch an instance with predefined instance ID ?

Issue

• May you advise if it's possible to launch an instance with predefined ID ? Or , if there is some very unique piece of data can be sticked to the instance during the boot strap ?
• Doing a nova list gives:

# nova list 
+--------------------------------------+--------------------+--------+------------+-------------+------------------------+
| ID                                   | Name               | Status | Task State | Power State | Networks               |
+--------------------------------------+--------------------+--------+------------+-------------+------------------------+
| f50f60a8-2fb7-43be-9916-63c8f7d11fe4 | anande             | BUILD  | spawning   | NOSTATE     | private=192.168.1.1    |
+--------------------------------------+--------------------+--------+------------+-------------+------------------------+

• I'm talking about ID f50f60a8-2fb7-43be-9916-63c8f7d11fe4 in the above output.
• We need to know something unique for a VM . Instance name is not relevant since you can launch as many VM with the same name as you want .
