>>Why do we need hotplug?
I was talking about hotplug devices on pci bridge. But bridge hotplug works also.

>>We simply add that at start time? 
yes, but maybe only if we need devices on this bridge ?
maybe it'll break live migration if we migrate a vm without bridge to vm with bridge ? 


seem to work fine like this:
-device pci-bridge,id=bridge1,bus=pci.0,chassis_nr=1,addr=0x..

and replace on device bus=pci.0 by bus=bridge


I'll do more test this weekend with differents os.

Yes, we still need that to support more network devices.

Why do we need hotplug? We simply add that at start time?
