Motivation: bridging or routing is required to enable a connection to bemade inward to a QEMU VM. TAP seems like the best of the availablesolutions. But connecting to a TAP device produces an error when theQEMU bridge helper fails.
Example:
g1@g1 ~/src/vmb$ qemu-system-x86_64 -net user -net bridge -net nic,model=virtio -enable-kvm -m 4096 -k en-us -display curses /home/g1/src/vmb/tmp/img6/vm.imgfailed to parse default acl file `/gnu/store/1072khbm9124a8a1pyyyw4mr1p12jsfq-qemu-2.6.0/etc/qemu/bridge.conf'qemu-system-x86_64: -net bridge: bridge helper failed
This error was produced with the attached 'img-tap' script. e.g., tobuild the vm ...
./img-tap mk 1
To (attempt to) run the vm ..
./img-tap run 1

Since a lot of things changed, is this bug report still relevant? Ifyes, what could be the next actionable step? Otherwise, let close it ormark it as wishlist.
