vctl runでエラーが出る場合
$ vctl run -n myNginx -t -d nginx ERROR failed to stop a sandbox, err:error code:exit status 255, message:Error: The virtual machine is not powered on: /Users/shtanaka/.vctl/.r/vms/myNginx/myNginx.vmx module=libcrx package=sandbox ERROR failed to create container: error code:exit status 255, message:2020-09-17T15:18:02.740| ServiceImpl_Opener: PID 35878 Error: The operation was canceled

sudo付きで実行する
$ sudo vctl run -n myAlpine -t -d alpine INFO container myAlpine started and detached from current session $ vctl stop myAlpine WARNING container myAlpine did not stop within 10 second, force kill it... INFO container myAlpine has been stopped
sudo付きで実行した後は、sudo無しで実行可能
