Qt for Device Creation

• If the emulator can not be started from within creator try the following steps:
  • Start desired virtual machine from virtualbox and ping 192.168.56.101
    • If the emulator can not be reached check your virtual box network adapter settings (see http://doc.qt.io/QtForDeviceCreation/qtee-installation-guide.html#2-installing-virtualbox)
  • Connect to the device via ssh and ping 192.168.56.1 from the device
    • If the host can not be reached check your firewall settings.
