it works fine.
You should enable monitor mode with airmon-ng instead of iwconfig,
By this way you will avoid conflict with network manager.
Check also the configuration of your virtual machine
Mode live or dual boot is more recommended.

Dude u didn't understood me I use airmon-ng start wlan0 to start monitor.After that just check with iwconfig to segure it is on and it changes to wlan0mon.After that I statrt airodump-ng wlan0mom it starts but no results show
