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. -- mit freundlichen Grüßen / best regards Günther J.
