Running tests on remote machine and capture output using pytest

Question

If I execute tests on local machine, I can see the console output from the test case. However, the console output is not captured while running tests on remote machine using pytest. Here is the sample test case -

test_sample.py

import os
import pytest

@pytest.mark.set1
def test_command():
    output = os.popen("ifconfig")
    print(output.read())

pytest.ini

[pytest]
markers =
    set1: mark a test as a set1.
    set2: mark a test as a set2.

~/.ssh/config

Host ubuntu
    HostName 10.203.114.68
    User root
    Port 22
    IdentityFile ~/.ssh/id_rsa

Pytest Command to execute tests on local VM

py.test -s -m set1 -k test_command -v

Console Output

**My pytest version on both local and remote vm ==> **

[root@localhost]$ python3.6 -m py.test --version
pytest 6.0.2

I have already verified that --capture / -s option is supported by the latest pytest-xdist
https://github.com/pytest-dev/pytest/issues/680

There is NO need to apply the following workaround
pytest + xdist without capturing output?
