Re: [Qemu-devel] tun interface

[Renzo Davoli]

Both actions (change tuntap permissions) and sudo permission for
ifconfig are deprecated for security.

If you are running qemu on your own computer this can be a minor
problem, although can be a hint in case of intrusion.
The Unix family have had minor problems (I'd say no problems) with
viruses & Co. for the clear multiuser approach and 
policy of access permission.

Anyway if you plan to run qemu in public places (e.g. a University lab)
tuntap permissions and sudo cannot be changed, if you do not like
risks.

P.S. vde was designed also for this problem. NB it is not an
advertisement.
