Hello
I have recently had to reinstall Centos 7.5 to on host computer. I have not be able to set-up qemu to support the q35 chip set. I have several virtual machines that require q35. This is not my first install, I have configured libvirt on many machines in the past, it just worked, it has not required any manual configuration.
[root@sj aadmin]# /usr/libexec/qemu-kvm -machine help Supported machines are: none empty machine pc RHEL 7.0.0 PC (i440FX + PIIX, 1996) (alias of pc-i440fx-rhel7.0.0) pc-i440fx-rhel7.0.0 RHEL 7.0.0 PC (i440FX + PIIX, 1996) (default) rhel6.6.0 RHEL 6.6.0 PC rhel6.5.0 RHEL 6.5.0 PC rhel6.4.0 RHEL 6.4.0 PC rhel6.3.0 RHEL 6.3.0 PC rhel6.2.0 RHEL 6.2.0 PC rhel6.1.0 RHEL 6.1.0 PC rhel6.0.0 RHEL 6.0.0 PC

I have installed the Virtualization Host group. Configured the nvram in the /etc/libvirt/qemu.conf, I even used the same copy from a previous installation.
nvram = [ "/usr/share/OVMF/OVMF_CODE.secboot.fd:/usr/share/OVMF/OVMF_VARS.fd",
"/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd:/usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd" ]
Thank you Aaron
