ModuleNotFoundError: No module named 'virtManager'

I've tried to compile a custom libvirt+libvirt-python+virt-manager stack following these tutorials :

on my jetson nano (arm64 + ubuntu 18.04)

In details,these are the steps that I did :

1) Install Git and clone both upstream libvirt and qemu repos.

2) Configure and build the qemu code and then install the qemu code. The make install command creates the binary files in the /usr/local directory.

cd qemu
mkdir -p build
cd build
../configure --prefix=/usr/local --target-list=aarch64-softmmu,arm-softmmu --enable-guest-agent --enable-vnc --enable-vnc-jpeg --enable-vnc-png --enable-kvm --enable-spice --enable-sdl --enable-gtk --enable-virglrenderer --enable-opengl
make -j
sudo make install

3) Configure and build libvirt and then install the libvirt code. Libvirt_build contains the log and configuration files for the daemons and the qemu driver.

cd ~/Desktop/zi/Work/I9/libvirt
mkdir -p libvirt_build
cd libvirt
$ meson build --prefix=~/Desktop/zi/Work/I9/libvirt/libvirt_build
$ ninja -C build
$ sudo ninja -C build install

4) Run the following commands from the $HOME/libvirt/build directory to start the libvirt daemon (libvirtd).

~/Desktop/zi/Work/I9/libvirt/build# sudo ./run src/virtlockd & sudo ./run src/virtlogd & sudo ./run src/libvirtd

5) Here is the output of the virt process running in my system.

root@zi-desktop:~/Desktop/zi/Work/I9/libvirt# ps axf | grep virt

30929 pts/0 S 0:00 | | \_ src/virtlockd
30926 pts/0 S 0:00 | \_ sudo ./run src/virtlogd
30930 pts/0 S 0:00 | | \_ src/virtlogd

31413 ? S 0:00 /usr/sbin/dnsmasq --conf-file=/root/Desktop/zi/Work/I9/libvirt/libvirt_build/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/home/zi/Desktop/Work/I9/libvirt/build/src/libvirt_leaseshelper

31426 ? S 0:00 \_ /usr/sbin/dnsmasq --conf-file=/root/Desktop/zi/Work/I9/libvirt/libvirt_build/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/home/zi/Desktop/Work/I9/libvirt/build/src/libvirt_leaseshelper

In this process, everything being run from ‘/usr/sbin’ is from the system based libvirt OS installation. The virt process that has been run as sudo is from custom libvirt. This indicates that you can have system-based libvirtd daemon and custom libvirtd daemon both running at the same time.

6) Install libvirt-python next because we need to use virt-manager and that requires libvirt python bindings

~/Desktop/zi/Work/I9/libvirt-python-7.3.0# export PKG_CONFIG_PATH=/home/zi/Desktop/Work/I9/libvirt/libvirt_build/lib/aarch64-linux-gnu/pkgconfig:$PKG_CONFIG_PATH

~/Desktop/zi/Work/I9/libvirt-python-7.3.0# python build
# python install --root /home/zi/Desktop/Work/I9/libvirt/libvirt_build

7) Then I've installed a custom virt-manager into the same location :

# cp -r virt-manager-3.2.0 /home/zi/Desktop/Work/I9/libvirt/src
# cd virt-manager-3.2.0
# python install --root /home/zi/Desktop/Work/I9/libvirt/libvirt_build

Finally I've put all in my $PATH:

export PATH=$CUSTOM_ROOT/usr/bin:$PATH


# /home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/bin# ./virt-manager

Unfortunately,the virt-manager does not work.

/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/bin# ./virt-manager

Traceback (most recent call last):
File "./virt-manager", line 6, in <module>
from virtManager import virt manager
ModuleNotFoundError: No module named 'virtManager'

/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/bin# virt-manager

Traceback (most recent call last):
File "/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/bin/virt-manager", line 6, in <module>
from virtManager import virt manager
ModuleNotFoundError: No module named 'virtManager'

What can I do now ?
