I run VTS test suite and my tests fail 100% with this consistent error:

AdbError: Error executing adb cmd 'adb -s 10.1.1.5:5555 reverse tcp:5010 tcp:1489'. ret: 1, stdout: , stderr: error: more than one device/emulator
AdbError: Error executing adb cmd 'adb -s 10.1.1.5:5555 reverse tcp:5010 tcp:1922'. ret: 1, stdout: , stderr: error: more than one device/emulator

AdbError: Error executing adb cmd 'adb -s 10.1.1.5:5555 reverse tcp:5010 tcp:3753'. ret: 1, stdout: , stderr: error: more than one device/emulator

The message is stderr: error: more than one device/emulator but if I list with adb devices I get only one device

List of devices attached
10.1.1.5:5555   device

same in VTS prompt:

vts-tf > l d
Serial                  State   Allocation  Product         Variant         Build            Battery  
10.1.1.5:5555       ONLINE  Allocated   dev_prod    dev_prod    6/22/2018.025   100

My connection with the device under test is not over USB but over Ethernet.

Why adb sees more than one device/emulator since that is not the case ?

Does anyone knows at what serves port 5010 and why is being redirected (reverse) to random ports 1489, 1922, 4950, etc?

Seems that it doesn't work on an adb connection over Ethernet and you need an adb connection over USB.

Since the build was on a server I found this workaround to run the vts on the machine that is directly connected via USB to the DUT following these steps:

1) restart DUT

2) kill the old adb and check USB connected

sudo killall -9 adb
adb devices

3) then try to run the vts from the build on the server, by mounting via sshfs:

sudo apt-get install sshfs
mkdir android
sudo groupadd fuse
sudo modprobe fuse
sudo adduser $USER fuse
fusermount -uz ./android
sshfs user@server:/storage/user/android-build/ ./android
cd android
cd ./out/host/linux-x86/vts/android-vts/tools/
pushd `pwd` && cd ./out/host/linux-x86/bin && export PATH=$PATH:$(pwd) && popd
./vts-tradefed
