Confusing permission errors really implicate udev issues with /dev/kvm about fimage

I'll be sure to implement that command into the documentation.

Hey ma dude, did you install qemu-kvm and add your user to the kvm group?

[carbonatedcaffeine]

Cause thats what you need to do to get KVM working correctly.

If you read the link I pointed to, you'll see that qemu-kvm is not actually required, but the udev rule it includes is required.

The Fuchsia emulator needs KVM. It won't work unless you enable it.

@EnderNightLord-ChromeBook I think thats understood, the issue here is that Ubunut 18.04 doesnt configure the permissions correctly, although i'm not able to reproduce this, seems to run out of the box on every other system I have.

I see

Ahh - linking to this from the README or some other documentation might help people diagnose kvm issues. I found it in
Set up and start the Fuchsia emulator (FEMU).

To verify that KVM is configured correctly, run the following command:

if [[ -r /dev/kvm ]] && grep '^flags' /proc/cpuinfo | grep -qE 'vmx|svm'; then echo 'KVM is working'; else echo 'KVM not working'; fi
