Hello:

 

I built kirkstone core-image-sato from scratch no mo= difications, clean build was going test kirkstone out…

When I went to run using qemu I saw the following is= sue with “tun”, even after a manual tun config I still got anot= her qemu error (see below):

 

(1)    Is this a known issue and how would I build in prop= er “tun” support for the core-image-sato/qemu  ?

(2)    How would I run “runqemu-gen-tapdevs” t= o manually create one for testing ?
