Thanks for the information. Since it's not clear whether the bridge configuration on the host is the problem, I suggest removing the bridge: Statically assign the tap interface on the host a local IP address like 192.168.5.1. Statically assign 192.168.5.2 inside the guest. See if guest and host can ping each other successfully. This will show whether the problem is QEMU's tap networking or whether the problem is the bridge configuration on the host.
