Answer 1

更改了/ home / folder / Android / Sdk / emulator /文件夹中的权限

chmod 777 -R /home/folder/Android/Sdk/emulator/

Answer 2

我遇到了这个问题，并且能够使用sudo chmod 777 / dev / kvm来解决它

Answer 3

您需要成为kvm组的一部分

尝试一下：

sudo adduser $USER kvm

然后重新启动android studio或注销/重新登录用户

Answer 4

在某些情况下，错误可能是由于用户对/ dev / kvm的权限不足 所以解决方案是给予许可。即

chmod 777 / dev / kvm
