So these are packets that are being sent from the bridge to the VM on the tap device, but getting dropped, probably because the tap device's queue is full. This would mean that the packets are not getting read by the VM fast enough, or may be not read at all after some point, since you see only the dropped increase after a while. So the issue is likely to be related to the virtualization software, rather than the bridge. Have you tried asking about this on forums related to the virtualization system you are using?
