Firstly I would make sure that all the packages are up to date. I'm
not sure
what the relevant versions are on CentOS 7.6.1810, so saying what
versio you
have installed might help later.
All installed packages are up to date.
This message actually doesn't look like it comes from libvirt. Are
there few more lines in a log somewhere?

As root? This would also make sense if the communication that fails
with the
above error is happening between libvirtd and systemd (when the daemon is
started by systemd).

I'm not really sure what the daemon is supposed to tell systemd apart
sd_notify() when it is starting. Maybe it is some value from the
environment that we're sending and the error originates there,
actually. Like the hostname or something similar. Again, having more
logs would help as I too don't really know what is going on in there.

I turned logging up to maximum. That's all I get:
