I have two identical server (SuperMicro) Ram CPU usw.

One is running CentOS 7  with KVM clients (5 Clients), all are installed with 
UEFI from github (repository https://www.kraxel.org/repos/jenkins)
[qemu-firmware-jenkins]
edk2.git....ovmf

this is working perfect, I can also pass through my network cards (hardware) 
usw.

with CentOS 8 it is possible to install only ONE KVM Client with UEFI and pass 
through hardware. when i install a second KVM client the system crash?

When I make a Installation without UEFI the installation is working ??

It is also possible to install a minimal Install of KVM Client with UEFI but 
afterward when I add Hardware with virsh or virt-manger the client crash on 
startup.
