Also, if you happen to upgrade hosts from 4.1 to 4.2 and CentOS 7.4 to CentOS 7.5 (specifically libvirt 3.2 to 3.9) make sure that you have the host in Maintenance first and there are no VMs running on the host during upgrade! Neglecting to do so will result in corrupting your VM configuration and such VMs will no longer start in future. There is no other fix than manually fixing the database configuration for each VM or recreate them in GUI. For each and every host update the host needs to be in Maintenance. Preferably use the GUI to upgrade them.
