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 On 29/05/2021 14:57, Mario Marietto wrote: > > Hello. > > > I've tried to compile a custom libvirt-python+virt-manager stack > following these tutorials : > > > https://developer.ibm.com/technologies/linux/tutorials/compiling-libvirt-and-qemu/ > <https://developer.ibm.com/technologies/linux/tutorials/compiling-libvirt-and-qemu/> > > https://gist.github.com/ffledgling/9e06ee32431d9a8f6d9bec3a0db35634 > <https://gist.github.com/ffledgling/9e06ee32431d9a8f6d9bec3a0db35634> > > > on my jetson nano (arm64 + ubuntu 18.04).
