I'm going to suggest that a better way to do VM-to-host or VM-to-VM communication would be to write an OpenFabrics (www.openfabrics.org) driver that uses hypercalls. There is probably some gotcha I am not aware of, but I think this would allow direct userspace to userspace communication between a process running on a host, and a process running on a VM, while still maintaining isolation. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
