Yes, this is only for testing
I am using the oVirt nodes (engine + 3 hosts) all installed on a
physical host (SuperMicro SYS-E200-8D)

You need in the VMs to have the 'vmx' flag, if you are using libvirt
you most likely should use 'host-passthrough' mode, otherwise nested
virtualization might not work. Regardless of the emulated CPU type,
you need to ensure 'vmx' flag is there, this can also be done
explicitly in the libvirt XML.
If this is only for testing - I may suggest using oVirt system tests,
which will do all these steps for you and setup a working oVirt
environment(engine + 2 hosts). But, you will need to run it on a
physical host.

To setup nested KVM, I follow these
instructions(https://pve.proxmox.com/wiki/Nested_Virtualization)
to check if is enabled do ("kvm_intel" for intel cpu, "kvm_amd" for
AMD)
-root@proxmox:~# cat /sys/module/kvm_intel/parameters/nested
N
(N means it's not, to enable ("kvm-intel" for intel, "kvm-amd" for
AMD):)
# echo "options kvm-intel nested=Y" > /etc/modprobe.d/kvm-intel.conf
and reboot or reload the kernel modul
modprobe -r kvm_intel
modprobe kvm_intel
check again
-root@proxmox:~# cat /sys/module/kvm_intel/parameters/nested
Y
Question: what other settings need to be enabled in the guest vm?
See "test nested virt" at
https://fedoraproject.org/wiki/How_to_enable_nested_virtualization_in_KVM
Do we need this setting in the vm?
