It's probably not feasible without changes to OSes.
It isn't. Drivers don't work that way. Regards, Anthony Liguori
As the guest OS's TCP is being used, what do you do about IP address space conflicts?The user can choose what address is used for the host.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?) -- Jamie
