From: Zhang Bo <oscar.zhangbo@xxxxxxxxxx>
when we run the command 'virsh dommemstat xxx',
althrough memballoon's model is set 'none' in vm's XML,
it still reports an error in libvirtd.log.
error : qemuMonitorFindBalloonObjectPath:1042 : internal error: Cannot determine balloon device path
Apparently, if we don't set memballoon, we don't need to
set balloon device path.
