Operating System

Ubuntu 22.04

Docker Image

budtmo/docker-android:emulator_9.0

Expected behaviour

To start the thing and not throw the KVM permission error

Actual behaviour

It crashes saying the error This user doesn't have permissions to use KVM (/dev/kvm)

I tried fixing it following with what it was complaining about but found out there was no root user and that chmod 777 to /dev/kvm didn't work

egrep -c '(svm|vmx)' /proc/cpuinfo returns 2 so I have access to KVM

Hi @dxomg ,

the issue is not on docker image but on your host machine configuration. Please check if your used host user have access to kvm. I will close the ticket as it is not an issue on the project. Feel free to reopen if needed.

I'm no longer using the project but anyways I just wanted to clarify that yes, KVM was accessible and was specified on the post

I have the exact same issue, KVM is available on host, and host user has the necessary permissions.... Its role however is not available inside the container and I am not able to add it manually.
