Comment 2 Cole Robinson 2018-08-11 17:39:02 UTC 
This is due to libvirt's switch from yajl to jansson. There's an upstream bug tracking it. Only option in the meantime is to downgrade libvirt*

Comment 3 Jan Kurik 2018-08-14 08:37:09 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.
Comment 4 Pavel Hrdina 2018-09-27 10:49:43 UTC 
The latest build libvirt-4.7.0-1.fc29 should fix the issue, the jansson switch was reverted.
