Hi,
What is missing for multiple pci buses is
- a simple P2P bridge emulator for pc architecture
- seabios support
- DSDT for a new machine which has multi pci buses(IRQ routing)
Is this really needed?
IIRC there are (used to be?) multiport nic pci cards which are simply

Q35 IRQ routing is
Right now, qemu is internally ready to handle pci-to-pci bridge emulators
and it's quite easy to add a new simple p2p bridge emulator.
Just a single function to initialize vid/did and a single PCIDevinceInfo.
But it's difficult to use multi pci buses at the moment
because other part isn't ready.
Isaku,
Could you explain more on irq routing in dsdt and related code in qemu? I
encountered a problem: emulated user networking (-net nic -net user) cannot
work in my qemu-kvm+q35+pcie code. Your original q35 (pure qemu) works fine.
Thanks!

My Q35 chipset patch will provide this.
IMHO, what we really need is a way to specify bridges

Thanks. Does this work for e1000 as well?
Haven't tried. I don't know how various e1000 drivers would react.
Also, does it support pci hotplug?
No, but that's fixable down
