在 jenkins 构建期间运行 android 模拟器

问题描述

我已经安装了 Jenkins 并配置了一个在构建过程中运行模拟器的构建作业.但是当我执行作业时，我收到 jenkins 用户无权运行 kvm 的错误消息.我该如何解决它.

I have installed Jenkins and configured a build job with emulator running during build. But when I execute the job, I get error message that jenkins user doesn't have permission to run kvm. How can I fix it.

$ android list target
[android] Using Android SDK: /opt/android/sdk
$ adb start-server
* daemon not running. starting it now on port 5973 *
* daemon started successfully *
$ adb start-server
[android] Starting Android emulator

emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure KVM is properly installed and usable.

权限

$ ls -l /dev/kvm

$ groups jenkins
jenkins : jenkins

推荐答案

我已经设法解决了这个问题.

I have managed to fix the problem.

1. 安装 Qemu-KVM 和 cpu-checker:
   sudo apt install qemu-kvm cpu-checker
2. 检查 KVM 是否可用(作为 jenkins 用户):
   $ kvm-ok
INFO:/dev/kvm 存在
可以使用KVM加速
3. 创建组 kvm 并将 jenkins 添加到该组:
   addgroup kvm
usermod -a -G kvm jenkins
4. 更改 /dev/kvm 的组所有权:
   chgrp kvm/dev/kvm
5. 创建udev规则:
   $ sudo nano/etc/udev/rules.d/60-qemu-kvm.rules
KERNEL=="kvm", GROUP="kvm", MODE="0660"
6. 重启

1. Install Qemu-KVM and cpu-checker:
   sudo apt install qemu-kvm cpu-checker
2. Check if KVM is available (as jenkins user):
   $ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
3. Create group kvm and add jenkins to this group:
   addgroup kvm
usermod -a -G kvm jenkins
4. Change group ownership for /dev/kvm:
   chgrp kvm /dev/kvm
5. Create udev rule:
   $ sudo nano /etc/udev/rules.d/60-qemu-kvm.rules
KERNEL=="kvm", GROUP="kvm", MODE="0660"
6. Reboot
