The entire point of qemu-bridge-helper is that it can be run by non-privileged users, but once run it has root privileges. This is done by the binary having the "suid bit" set. If your distro didn't install it this way, that is a bug (an ls -l of the binary should show "rwsr-xr-x" permissions) . You can fix it with the chmod command (e.g. "chmod 4755 /usr/libexec/qemu-bridge-helper"). If that is what was broken, and you used the distro-built package, you should report it as a bug to the distro's bug tracking system. Beyond that, you need to read about the qemu-bridge-helper ACL file in the link I originally gave (along with other info you can find with a google search).
