mount -o remount,rw /
# adb remount
$ adb kill-server
$ adb connect xxx.xxx.xxx.xxx
If above doesn't work then type$ adb kill-server$ adb start-server$ adb connect :5555
$ adb connect xxx.xxx.xx.xx:5555
no, it doest not help, still I am getting in the virtual machine "unable to connect to localhost:5555: cannot connect to localhost:5555: No connection could be made because the target machine actively refused it. (10061)"
The above is not working. Problem not solved
