Description Mihai Prica 2013-08-26 14:39:08 UTC

1. Start a VM with a tap interface. Qemu can be used for this.
(ex: qemu-system-x86_64 -net nic,model=virtio -net tap,vlan=0,ifname=tap0,script=no,downscript=no,vhost=on ***Image***)
2. In parallel, run a yocto image using runqemu.

The script will fail because it will try to acquire the tap interface set up by the VM started at 1.

In such situation, I think what we can do is to provide the user more information.

And at a minimal, we should let the user know how to make runqemu skip a specific tap interface.
