npm start failed to start nodeOS

[jumson]

There were no errors, only this console output:

ubuntu@ubuntu16:~/NodeOS$ npm start

> NodeOS@1.0.0-RC3 start /home/ubuntu/NodeOS
> scripts/start

ubuntu@ubuntu16:~/NodeOS$

after trying to run that script, I get this:

ubuntu@ubuntu16:~/NodeOS$ sudo ~/NodeOS/scripts/start
warning: TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5]
Could not initialize SDL(No available video device) - exiting

at this path:ubuntu@ubuntu16:~/NodeOS/out/x86_64/pc/qemu$
I ran this command, based on the qemu run.sh script, and it booted me into the REPL:
