ModuleNotFoundError: No module named 'virtManager : TUTORIAL REDONE BETTER

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I've tried to compile a custom 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.

git clone

git clone

  1. 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

2.1) qemu 6.0 has been detected correctly at this point :

#qemu-system-aarch64 --version

QEMU emulator version 6.0.50 (v6.0.0-1145-g7258034ab4) Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers

  1. 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 ~/Desktop/zi/Work/I9/libvirt

$ meson libvirt_build

$ ninja -C libvirt_build

$ ninja -C libvirt_build install

  1. Run the following commands from /root/Desktop/zi/Work/I9/libvirt/libvirt_build directory to start the libvirt daemon (libvirtd).

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

  1. Here is the ouput of the virt process running in my system :

~/Desktop/zi/Work/I9/libvirt_build# ps axf | grep virt

30925 pts/0 S 0:00 | _ sudo ./run src/virtlockd 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 31201 pts/0 S 0:00 |
_ sudo ./run src/virtlockd 31205 pts/0 S 0:00 |
| _ src/virtlockd 31202 pts/0 S 0:00 |
_ sudo ./run src/virtlogd 31207 pts/0 S 0:00 |

_ sudo ./run src/libvirtd 31206 pts/0 Sl+ 0:01 |
_ src/libvirtd 4732 pts/1 S+ 0:00 _ grep --color=auto virt

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

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

~/Desktop/zi/Work/I9/libvirt/libvirt_build# sudo ./run tools/virsh list --all

  1. Install libvirt-python next because I need to use virt-manager and that requires libvirt python bindings


mkdir - p $CUSTOM_ROOT/src

#cp -r /root/Scrivania/Scrivania/Dati/Data/Nano/I9/Tools/virt-manager-3.2.0 /home/zi/Desktop/Work/I9/libvirt/libvirt_build/src

~/Desktop/zi/Work/I9/libvirt/libvirt_build/src/libvirt-python-7.3.0# export LD_LIBRARY_PATH=$CUSTOM_ROOT/lib

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

~/Desktop/zi/Work/I9/libvirt/libvirt_build/src/libvirt-python-7.3.0# python build

~/Desktop/zi/Work/I9/libvirt/libvirt_build/src/libvirt-python-7.3.0# python install --root $CUSTOM_ROOT


  1. Then I've installed a custom virt-manager into the same location and it should pick up the newer python bindings :

#cp -r /root/Scrivania/Scrivania/Dati/Data/Nano/I9/Tools/virt-manager-3.2.0 /home/zi/Desktop/Work/I9/libvirt/libvirt_build/src

#cd virt-manager-3.2.0

#python install --root $CUSTOM_ROOT


  1. Finally I put all in my $PATH :


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

#echo $PATH

/home/zi/Desktop/Work/I9/libvirt/libvirt_build/usr/bin:/home/zi/Desktop/Work/I9/libvirt/libvirt_build/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/zi/Desktop/Work:/root/Desktop/turbovnc/jtx1_remote_access >/tmp/turbovnc-build/bin/:/root/Desktop/turbovnc/jtx1_remote_access/tmp/virtualgl-build/bin/

  1. Unfortunately,when I try to run virt-manager with this command,it does not work :

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

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

Where is the mistake ? Thanks very much.
