Hi,
Looks like netdev bridge have no support for vhost=on switch. Would be
ince if that could be added.

Try -netdev tap,helper=/path/to/qemu-bridge-helper,vhost=on,...

Sadly, -netdev tap does not support br= so I can't specify the bridge
for helper.
And I can't pass the '--use-br=' argument for helper= tap's option so no
workaround here.

You should be able to pass a command line like this:
-net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=br0"

Qemu treat it as one, single command as a whole. :<
sh: /usr/libexec/qemu-bridge-helper --br=lebridge0: not found
failed to launch bridge helper
qemu-system-x86_64: -netdev
tap,id=if0,helper="/usr/libexec/qemu-bridge-helper --br=lebridge0":
Device 'tap' could not be initialized

Nah, it does work. I just failed a bit while doing exec() in perl so I
passed double quotes to qemu instead of just telling /bin/sh to treat it
as single argument.
Thank you guys.
