We need something like a "PCI proxy" allowing to route some I/O to virtua= l PCI devices and others to real PCI devices. Moreover we must be able to infor= m host kernel to not manage a given PCI card (or be able to hot unplug it from h= ost kernel PCI structures) Laurent --=20 ---------------- Laurent.Vivier-6ktuUTfB/bM@public.gmane.org ----------------- "Given enough eyeballs, all bugs are shallow" E.
