Hi folks!

I'm trying to connect to a self-compiled libvirt 9.10.0 from python, but get the following error:

...

...

...

import libvirt as lv conn = lv.openReadOnly(None)

Python 3.12.0 (main, Oct  3 2023, 19:47:47) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. libvirt: DBus Utils error : error from service: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.libvirt.unix.monitor is not registered Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "/home/user/sw/python3/lib/python3.12/site-packages/libvirt.py", line 349, in openReadOnly    raise libvirtError('virConnectOpenReadOnly() failed') libvirt.libvirtError: error from service: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.libvirt.unix.monitor is not registered

What is the issue here? Also, I've grepped the error in any source but found nothing!

That's because this error message does not come from libvirt but PolicyKit. I suspect that either you did not install "*.policy" files: /usr/share/polkit-1/rules.d/50-libvirt.rules /usr/share/polkit-1/actions/org.libvirt.unix.policy /usr/share/polkit-1/actions/org.libvirt.api.policy or you did, but polkit daemon wasn't restarted (though I would have sworn it can reload rules dynamically).
