I'm just getting into KVM and trying to figure everything out, and I don't see a step-by-step guide to configuring a host/guest system with either SR-IOV or Intel's VMDq. For SR-IOV I assume I need to configure the PF in the host, enable some number of VFs, pass through a VF to each guest and load the vf driver. Is that right? Do I need to configure a software bridge to allow the guests to talk to each other? I assume the passthrough require VT-d support in the hardware and host kernel--is that correct?
