Maybe it's just a documentation thing. 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.
You can use virt-manager; it has a GUI for that. Once you're comfortable with it you can drop down to virsh command line and from there to raw qemu command line / monitor.
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?
I think all that is needed is to prevent the host from binding to the guest - not sure.
Do I need to configure a software bridge to allow the guests to talk to each other?
S/R-IOV networking is beyond my knowledge - I think it depends on your switch, sometimes it will loop back packets to other guests, other times the NIC itself will do that. It may just work, so try it out.
I assume the passthrough require VT-d support in the hardware and host kernel--is that correct?
Yes. Recent kernels have that. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
