[Qemu-devel] multifunction pci virtio-blk devices

[Hui Kai Ran]

Hi,

It seems that qemu now have the ability to install pci device with 
mutlifunction=on, such as
I got a cfg file to start qemu
[device "ehci"]
  driver = "ich9-usb-ehci1"
  addr = "0d.7"
  multifunction = "on"

[device "ehci1"]
  driver = "ich9-usb-ehci1"
  addr = "0d.3"
  multifunction = "on"

[device "ehci2"]
  driver = "ich9-usb-ehci1"
  addr = "0d.4"
  multifunction = "on"

[device "ehci3"]
  driver = "ich9-usb-ehci1"
  addr = "0d.5"
  multifunction = "on"

I end up with four usb controllers in one slot.

but for virtio blk device , how can i open multifunction ability?

Thanks.
