Please find the full output attached with this mail. My first future advice would be never install software into your OS in any way than distribution packager, in CentOS case yum/rpm. It is not trivial to remove all the files installed by make install or setup.py install as the files are not tracked by anything. > After this when I tried to launch Virtual Machine Manager from > Applications->System Tools-->Virtual Machine Manager, I don't see it > launched. > If I try to launch it via command line I get the following > > > [root@Mordor aravind]# virt-manager > Traceback (most recent call last): > File "/usr/share/virt-manager/virt-manager", line 19, in <module> > from virtinst import BuildConfig > File "/usr/share/virt-manager/virtinst/__init__.py", line 42, in <module> > _set_libvirt_error_handler() > File "/usr/share/virt-manager/virtinst/__init__.py", line 32, in > _set_libvirt_error_handler > import libvirt > ModuleNotFoundError: No module named 'libvirt' > > > I do have libvirt installed. This means that there is missing python libvirt module. There is only libvirt-python package which provides only python 2.7 files and I checked that there is no libvirt-python3.6 nor python3.6-libvirt in EPEL so you would have to build it by yourself. virt-manager-1.5.0 is python 2 only and since virt-manager-2.0 we switched to python3 only. > [root@Mordor aravind]# rpm -qa | grep libvirt > libvirt-daemon-driver-storage-gluster-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-config-network-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-nodedev-4.5.0-10.el7_6.12.x86_64 > libvirt-gobject-1.0.0-1.el7.x86_64 > libvirt-daemon-driver-qemu-4.5.0-10.el7_6.12.x86_64 > libvirt-client-4.5.0-10.el7_6.12.x86_64 > libvirt-glib-1.0.0-1.el7.x86_64 > libvirt-daemon-driver-storage-core-4.5.0-10.el7_6.12.x86_64 > libvirt-gconfig-1.0.0-1.el7.x86_64 > libvirt-daemon-driver-lxc-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-disk-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-secret-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-mpath-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-kvm-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-nwfilter-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-iscsi-4.5.0-10.el7_6.12.x86_64 > libvirt-bash-completion-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-config-nwfilter-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-scsi-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-interface-4.5.0-10.el7_6.12.x86_64 > libvirt-python-4.5.0-1.el7.x86_64 > libvirt-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-network-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-4.5.0-10.el7_6.12.x86_64 > libvirt-libs-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-logical-4.5.0-10.el7_6.12.x86_64 > libvirt-daemon-driver-storage-rbd-4.5.0-10.el7_6.12.x86_64 > > Please help me restoring the working version of Virtual Machine or making > this new version work. To make the new virt-manager work you would have to build libvirt-python bindings for python3.6 by yourself and install it into your system which I would not recommend. To fix your old virt-manager you can try: yum reinstall virt-install virt-manager virt-manager-common which should replace all required files to fix the distribution version. Pavel
