Instrumented tests with an emulator for an Android App project - KVM support problem

GitLab CI/CD
1

I want to run a pipeline that includes android app instrumented tests, which require an android emulator.

I am using the image: nvcr.io/nvidia/cuda:12.1.1-base-ubuntu22.04

(from GPU-enabled hosted runners | GitLab)

I want an image that will allow me to run android emulator which requires hardward acceleration.

Although I have installed KVM, when I run

kvm-ok

I am getting the error:

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

What do I need to do to fix this?

This is my .gitlab-ci.yml file:

image: eclipse-temurin:17-jdk-jammy

variables:

  # ANDROID_COMPILE_SDK is the version of Android you're compiling with.
  # It should match compileSdkVersion.
  ANDROID_COMPILE_SDK: "34"

  # It's what version of the command line tools we're going to download from the official site.
  # Official Site-> https://developer.android.com/studio/index.html
  # There, look down below at the cli tools only, sdk tools package is of format:
  #        commandlinetools-os_type-ANDROID_SDK_TOOLS_latest.zip
  # when the script was last modified for latest compileSdkVersion, it was which is written down below

The mixlrdev/nvcr-io-nvidia-cuda-12-1-1-base-ubuntu22-04-kvm:latest is built with the following Dockerfile:

FROM nvcr.io/nvidia/cuda:12.1.1-base-ubuntu22.04 

# Install necessary packages
RUN apt-get update && \
    apt-get install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils kmod virt-manager && \
    groupadd kvm && \

# Ensure libvirtd is started
RUN systemctl enable libvirtd

# Expose necessary ports
EXPOSE 5900 16509

# Start libvirtd
CMD ["/sbin/init"]

It seems like a long pending issue. Running Android emulator in Gitlab provided runners seems still not resolved.
