Inform to the Guest some Client's ID

Hello,

We are trying to setup a VDI solution in RHEV 3.3.
So far we have make everything works fine, but in our scenario we need to make some change in the software running inside de VM based on the place where the VDI Client is located.

For example:

Let's say we have a VDI Client in the Room A , named room-a.example , in that room we also have a printer ( printer-a.example ).
This client connects to the Windows Pool an got a VM from the pool.
We want to tell the OS inside the VM , some information about the client in order to configure printer-a.example as the default printer inside the VM.

Anyone knows or have an idea about how to pass that kind of information.
I don't care how it's passed, could it be an enviromental variable o some file in inside the VM.

All our VMs runs the RHEV's guest-agent.

Regards.
