Public bug reported:
qemu output:
access denied by acl file
qemu-system-ppc64: bridge helper failed
Option description:
-netdev bridge,id=id[,br=bridge][,helper=helper]
Connect a host TAP network interface to a host bridge device.
Use the network helper helper to configure the TAP interface and attach it to the bridge. The default network
helper executable is /path/to/qemu-bridge-helper and the default bridge device is br0.
Examples:
#launch a QEMU instance with the default network helper to
#connect a TAP device to bridge br0
qemu-system-i386 linux.img -netdev bridge,id=n1 -device virtio-net,netdev=n1
#launch a QEMU instance with the default network helper to
#connect a TAP device to bridge qemubr0
qemu-system-i386 linux.img -netdev bridge,br=qemubr0,id=n1 -device virtio-net,netdev=n1
What is the acl file? What is the interface to qemu-bridge-helper?

Also this is what bridge.conf contains:
# Access control file for qemu bridge helper
# Syntax consists of:
# # comment (ignored)
# allow all
# allow <bridge_name>
# deny all
# deny <bridge_name>
# include /path/to/additional/ACL/file
# Users are blacklisted by default and 'deny' takes precedence over 'allow'.
# Including additional ACL files allows file access permissions to be used as
# a component of the policy to allow access or deny access to specific bridges.
How are users specified? Or is the mention of users bogus?
