尝试启动仿真器时出现此错误是什么意思？

Question

我正在使用Eclipse 4.4(Luna)并试图启动一个模拟器来测试我的android应用程序，但出现以下错误：

Starting emulator for AVD 'droidX'
WARNING: Data partition already in use. Changes will not persist!
WARNING: SD Card image already in use: C:\Users\world_000\.android\avd\droidX.avd/sdcard.img
WARNING: Cache partition already in use. Changes will not persist!
emulator: Failed to open the HAX device!
HAX is not working and emulator runs in emulation mode
emulator: Open HAX device failed
creating window 0 0 238 423

模拟器在黑屏上打开，中间写着android ，然后我尝试将应用程序作为android application并获得以下消息：

[2014-08-09 10:34:17 - FirstApp] Android Launch!
[2014-08-09 10:34:17 - FirstApp] adb is running normally.

[2014-08-09 10:34:17 - FirstApp] Launch canceled!

有人可以解释为什么我会收到这些错误以及如何解决这些错误吗？

WARNING: Data partition already in use. Changes will not persist!
WARNING: SD Card image already in use: C:\Users\world_000\.android\avd\droidX.avd/sdcard.img

表示您正在尝试打开已经打开的模拟器。关闭该模拟器，然后尝试打开。
