Hi Avi,

I think the issue is that QEMU is trying to launch an X application but doesn’t have a DISPLAY environment variable. If the shell running QEMU is on the same system as your primary Ubuntu GUI, running:

> export DISPLAY=:0

should fix this.

Hmm. It may be because you are running as root but your GUI is running as a different user. You should be able to run mender-convert and the QEMU stuff without being root. I would try that before troubleshooting any further.
