Hi, what is your OS and version of virt-manager and libvirt?

[bojansimicmb]

Hi, Ubuntu 18.04.3, virt-manager is 2.2.1 and libvirt 4.0.0

[phrdina]

Thanks for the info, it confirms my suspicion. You have libvirt 4.0.0 and probably libvirt-python 4.0.0 where there is no baselineHypervisorCPU API. I'll improve the code to properly handle this case and use older API if the new one is missing. Thanks for the report.

Yes, python3-libvirt is 4.0.0. No problem.
