Oh, I don't have added yet the hotplug part.
I was waiting that you commit this first.

Objet: RE: [pve-devel] [PATCH] add pci-bridge support and bump MAX_NET and MAX_VIRTIO to 32 devices
You simple call print_drivedevice_full() without bridges hash in vm_deviceplug()?
We do not need working hotplug, but we want at least some error message?
