-The "vbox_x86" product defines a non-hardware-specific target intended
-to run on the VirtualBox emulator.
-
-Most of the Android devices (networking, phones, sound, etc) do not work.
-
-ADB via ethernet works with this target. You can use 'adb install' to
-test applications that do not require network, phone or sound support.
-This emulation is useful because VirtualBox runs much faster then does the
-QEMU emulators (at least until a KVM enabled QEMU emulator is available).
