OK, lets compare versions:
CentOS 7.5: 3.10.0
Xubuntu 16.04: 4.4.0
In what way could that be, as you say, older?
/K
I have been able to at least prove it's not "your fault" :)
To test that I have installed another CentOS 7.5 VM as a L1 hypervisor,
just an ordinary CentOS from LiveGNOME ISO and in that VM installed
virt-manager and all to see if it's something specific to either _how_
you are starting the local engine VM or _what_ you are starting, like
if something's up with the appliance image.
Turns out that trying to boot the CentOS 7.5 LiveGNOME ISO inside the
L1 hypervisor yields the exact same result.
I am going to test this out in a Xubuntu 18.04 Host to see if that
changes anything.
