License management with virtual machines

Folks:

We are using virtual machines.  If we have a staff change or a corrupted virtual machine, we create a new virtual machine by duplicating an existing hard drive, creating a new virtual machine, and assigning the duplicate hard drive to the new machine.  Works beautifully.

The problem is that Acrobat thinks we have installed it on a new computer and therefore requires relicensing, and it won't re-license automatically because it thinks the license is in use already.

Is there a way around this problem?

Is there a way to convert our retail licenses to some kind of volume license where there is but one license code that can be used X number of times?

Thanks.
