Rather than changing guest ID to include host ID so as to make it 
globally unique (whereas it is currently host-specific), I think just 
populating the dedicated host ID attribute (UUID) on the guest would be 
enough, and far less intrusive.

Of course, the algorithm used on GLPI side to establish the relationship 
beween host and guest should be:
- virtual machine ID (HARDWARE/VMID element) on the guest should match 
virtual machine ID (VIRTUALMACHINE/VMID) on the host
- physical machine ID (HARDWARE/UUID element) on the guest should match 
physical machine ID (VIRTUALMACHINE/UUID) on the host

The first condition in enough only for virtualization technologies that 
use globaly unique virtual machine identifiers.
