Is there some existed way to do that, like remote IPC > in qemu? How would you communicate between two bare-metal hosts? Emulate that same setup in your two guests. You appear to be intent on setting up shared memory solutions, when I think the better thing is to focus on setting up efficient emulated network device solutions. Then your code will be portable no matter how the network device frontend is hooked up to the host backend (and it may be possible to have a host backend that uses shared memory for a very efficient network device emulation when two VMs are on the same host, but which can also be ported to work between VMs on different hosts by using regular networking - and that's what virtio-net is focusing on defining). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
