Hello Yaniv,

When migrating, these VMs can jump from a recent hardware host to an 
older one, with a different generation CPU (though of the same intel kind).

I read more about this WPA issue, and I also checked : all our licences 
are MAK_B kind, which I read everywhere that they should not induce such 
WPA trouble, once they are correctly registered (which I obviously take 
care of).
I also read the list of components that are checked to create a hashed 
key linked to the licence.
As you wrote, changing to many components is triggering a validity break.

Knowing this, may I ask you to comment on the promising "VM Custom 
Serial Number" Alex was talking about : it sounded perfect, but 
eventually not enough to cope with the hardware change?
