       vde_tunctl — create and manage persistent TUN/TAP interfaces


       vde_tunctl [-f clone-dev] [-u owner] [-g group] [-n] [-t dev-name]

       vde_tunctl [-f clone-dev] -d dev-name


       vde_tunctl  allows  the  host sysadmin to preconfigure a TUN/TAP device
       for use by a particular user.  That user may open and use  the  device,
       but may not change any aspects of the host side of the interface.

       vde_tunctl is an extension of tunctl.

       vde_tunctl  defines  tap  interfaces unless dev-name begins by "tun" or
       the option -n appears in the command line.


       To create an interface for use by  a  particular  user,  invoke  tunctl
       without the -d option:

       # vde_tunctl -u someuser
       Set 'tap0' persistent and owned by uid 500

       Then, configure the interface as normal:

       # ifconfig tap0 up
       # route add -host dev tap0
       # bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
       # arp -Ds eth0 pub

       To delete the interface, use the -d option:

       # vde_tunctl -d tap0
       Set 'tap0' nonpersistent

       To create or destroy a tun interface (instead of tap):
       # vde_tunctl -n -u someuser
       Set 'tun0' persistent and owned by uid 500
       # vde_tunctl -d tun0
       Set 'tun0' nonpersistent
