It would stop the OS from loading a NIC driver for it.
Then later, then vmchannel-using guest app would force the OS to load
a NIC driver for the alternative PCI ID. E.g. by loading a module on
Linux with an alternative name and some module arguments. It's
probably not feasible without changes to OSes.

So the vmchannel will need some guest-specific configuration before
the guest-host apps work? (And I don't mean OS-version-specific, but
specific to individual guest configs?)
