subprocess.check_output() has been introduced in Python 2.7, so the script will fail when trying to install stuff in guests with Python 2.6 and older (like RHEL 6 / CentOS 6, for example). Thus gracefully fallback to subprocess.Popen() when subprocess.check_output() is not available. Change-Id: I335148397932177810f095a942b993b249991107 Closes-Bug: #1415240
