                : machine).

How reproducible:

Reproducible on all machines I've tried.

Steps to Reproduce:
1. Install virt-install with dnf
2. Run virt-install with any arguments

Actual results:

During initialisation it will throw this:

Traceback (most recent call last):
  File "/usr/lib64/python3.14/site-packages/gi/importer.py", line 137, in create_module
    introspection_module = get_introspection_module(namespace)
  File "/usr/lib64/python3.14/site-packages/gi/module.py", line 244, in get_introspection_module
    module = IntrospectionModule(namespace, version)
  File "/usr/lib64/python3.14/site-packages/gi/module.py", line 104, in __init__
    repository.require(namespace, version)
    ~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^
gi.RepositoryError: Typelib file for namespace 'libxml2', version '2.0' not found

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/bin/virt-install", line 5, in <module>
    from virtinst import virtinstall
  File "/usr/share/virt-manager/virtinst/__init__.py", line 49, in <module>
    from virtinst.osdict import OSDB
  File "/usr/share/virt-manager/virtinst/osdict.py", line 13, in <module>
    from gi.repository import Libosinfo
  File "/usr/lib64/python3.14/site-packages/gi/importer.py", line 139, in create_module
    raise ImportError(e) from e
ImportError: Typelib file for namespace 'libxml2', version '2.0' not found

Expected results:

I can use virt-install to interact with libvirt
