[Qemu-devel] Virtio-pci issue

[Evgeny Voevodin]

Hi, guys!

While trying to refactor virtio-pci as continuation of my RFC
virtio-mmio patch series:
http://lists.gnu.org/archive/html/qemu-devel/2012-04/msg03665.html
I've faced a problem.

I try to create virtio-pci-transport device to which virtio-blk,net,etc
could be connected. Any board could create as many transport devices as
it wants and then any actual back-end could be connected to that
transport through a provided virtio-pci.x bus. virtio-pci-transport is
derived from TYPE_PCI_DEVICE.
The problem is that if I create transport devices and wish to connect
back-ends to them, each back-end would set its properties to the class,
not to the object.
For example, vendor_id property is different for blk and net, but since
they are both have same class PCIDeviceClass, they share that property.

How to deal with this?
