The manpage reflects that multiple -net user calls may be made,

multiple -net calls can be combined into one, and this patch adds
that information to qemu-options.hx. Also, -net user may only
be used in conjunction with -net nic. This is already implcitly
stated, but this patch makes that statement more explicit.
Actually, the problem is that the user created a loop. It's actually
valid to have something like:
-net user -net dump,file=foo.pcap -net nic
But having -net user -net user creates a loop.
When I used -net user -net user, it didn't hang: QEMU crashed with a
stack overflow.
It crashed after a doing a successful full OS install, because
everything was fine until the first network packet.
That's not nice, even if it is user error.
