[yocto] QEMU nfs kernel panic

[Zhang, Jessica]

Hi Jack,

The minimal-dev image doesn't contain tcf-agent which is needed for any remote interaction.  So can you build core-image-sato-sdk image and use it to boot up qemu, then your problem will be solved.

Thanks,
Jessica

Ok, I managed to fix it. I needed to load the tun module to get it
working. Maybe this should be added as a check in runqemu?

I am now having issues with connecting to the live image, I recieve a
connection refused message when I try to upload the file to the virtual
machine, I have just the stick minimal-dev image so no additional
passwords set.
