Recreate a vm keeping the same uuid

Hi everyone !

I have a question concerning the Nova component.

In fact, imagine I have a vm stucked in any state and it has never been active. I cannot evacuate, rebuild etc... The only thing I can do is to delete it and create a new one. My problem is that I have a system which is using directly the uuid of the vm created. Indeed, when you create a new vm, you get its uuid directly.

If there is a problem and it has never been active, you need to recreate a new one. But, you loose the uuid and the new vm will have another uuid.

So, how can I recreate a vm with the same uuid of the vm I delete ? Is there a replacing mechanism in Nova ?

Thanks guys !

Regards, Nicolas
