CPU加速状态：该用户无权在docker中使用KVM（/dev/kvm）

Question

我已经用 appium、java8、android sdk、节点 8.11.0、cucumber 和 ruby​​ 构建了一个 docker 创建设备后，我检查 kvm-ok

得到

   root@994d47ae73ce:/opt/android-sdk/emulator# kvm-ok                                                        
   INFO: /dev/kvm exists
   KVM acceleration can be used

当我执行

root@994d47ae73ce:/opt/android-sdk/emulator# emulator 
@Nexus_5X_API_24 -verbose -no-window -skin 1080x1920

然后

emulator: autoconfig: -kernel /opt/android-sdk/system-images/android-24/google_apis/x86//kernel-ranchu
emulator: Target arch = 'x86'

典型的解决方案是行不通的

sudo apt install qemu-kvm
sudo adduser $USER kvm
sudo chown $USER /dev/kvm

Answer 1

在您的主机上的 powershell 中，通过替换运行以下命令带有虚拟机的名称，当虚拟机处于关闭状态时

设置-VMProcessor-VMName-ExposeVirtualizationExtensions $true

现在启动虚拟机并转到终端并运行以下命令来安装 qemu-kvm： sudo apt install qemu-kvm

接下来，您需要使用以下命令 将用户 your- username添加到 kvm 组： sudo adduser username kvm

接下来，在某些情况下，还需要运行以下命令： sudo chown username e /dev/kvm

您可以使用以下命令获取您的用户名： whoami

现在，您可以使用以下命令验证您的用户名是否已添加到 kvm 组： grep kvm /etc/group
