Description Ke Zou 2016-04-12 07:46:19 UTC 
BA image URL:
http://autobuilder.yoctoproject.org/pub/releases/yocto-2.1.rc1/build-appliance/

how to reproduce:
unzip build-appliance image
use vmplayer to run 
in BA shell: build image(core-image-minimal)
try to runqemu with newly-built image
"runqemu qemuxxx nographic"

the printout:
sh-4.3$ runqemmu qemuarm nographic
TUN control device /dev/net/tun is unavailable: you may need to enable TUN (e.g. sudo modprobe tun)
Comment 1 Juro Bystricky 2016-04-13 18:26:54 UTC 
To remedy this with the existing BA:
1. Switch to root terminal "Terminal" from the default "Terminal <2>"
2. Run 
   # sudo modprobe tun
3. 
   # cd /sbin
   # ls -s /usr/sbin/iptables iptables

4. Switch to "Terminal <2>"

   $ runqemu qemux86


I'll try to modify the BA recipe so that the above steps are not needed.
