ModuleNotFoundError: No module named 'virtManager : TUTORIAL REDONE BETTER

Sat May 29 14:07:44 UTC 2021

Hi Mario,

The error message "ModuleNotFoundError: No module named 'virtManager'"
indicates that Python can't find where the virtManager module was installed.

To resolve this problem you may need to add the appropriate path to your
PYTHONPATH
<https://docs.python.org/3/using/cmdline.html#envvar-PYTHONPATH>
environment variable.

Example:

export
PYTHONPATH=$PYTHONPATH:/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/share/virt-manager

Best wishes,
Radostin
