The spapr_vio_find_by_reg() function in hw/spapr_vio.c is supposed to find

It does the first ok, but if no device with that reg exists, it just

We go to great lengths to restrict ourselves to just cap_net_admin as an OS
enforced security mechanism. However, we further restrict what we allow users
to do to simply adding a tap device to a bridge interface by virtue of the fact
that this is the only functionality we expose.
This is not good
With qemu it is possible to run a guest from an unprivileged user but if
we wanted to communicate with the outside world we had to switch
to root.
We address this problem by introducing a new network backend and a new
network option for -net tap. This is less flexible when compared to
existing -n
The ideal way to use qemu-bridge-helper is to give it an fscap of using:
setcap cap_net_admin=ep qemu-bridge-helper
Unfortunately, most distros still do not have a mechanism to package files
with fscaps applied. This means they'll have to SUID the qemu-bridge-helper
binary.
To improve security
This patch adds a helper that can be used to create a tap device attached to
a bridge device. Since this helper is minimal in what it does, it can be
given CAP_NET_ADMIN which allows qemu to avoid running as root while still
satisfying the majority of what users tend to want to do with tap devices
The most common use of -net tap is to connect a tap device to a bridge. This
requires the use of a script and running qemu as root in order to allocate a
tap device to pass to the script.
This model is great for portability and flexibility but it's incredibly
difficult to eliminate the need to ru
