Subject: bug#24156: QEMU '-net bridge' --> "qemu-system-x86_64: -net bridge: bridge helper failed"
Date: Thu, 04 Aug 2016 22:40:15 -0400 [thread overview]
Message-ID: <8637mk6ir4.fsf@gmail.com> (raw)

Motivation: bridging or routing is required to enable a connection to be
made inward to a QEMU VM. TAP seems like the best of the available
solutions. But connecting to a TAP device produces an error when the
QEMU 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.img
failed 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., to
build the vm ...
./img-tap mk 1
To (attempt to) run the vm ..
./img-tap run 1
Running Guix built from git checkout on GuixSD:
stat ~/.config/guix/latest | grep File:
File: '/home/g1/.config/guix/latest' -> '../../src/guix'
g1@g1 ~/src/vmb$ git -C ~/.config/guix/latest describe
v0.11.0-242-g7ccb874
