Re: [Qemu-devel] eth0 problems

[Lonnie Cumberland]

Is there a way for me to tell if the TUN module has been compiled into 
this kernel?

I looked at the src for the kernel via the "make menuconfig" and it 
showed the TUN/TAP device as a Module. Also the module exists in the 
/lib/modules directory.

how can I load the tun module?

Thanks,
Lonnie
