But one of the questions already asked to you also throughout the other thread was: what hypervisor are you using?
CentOS-7 v 1611 Question << What hypervisor should I be using??
More precisely, as it is clear it is Qemu-KVM, what is the way you start your VMs that are the candidates to become hypervisors in oVirt?
Not sure I understand this question?
Is it with virt-manager, as described in one of the links you provided, or direct virsh commands or what?
Virt-Manager
If you are using virt-manager, what did you specify in CPUs --> Configuration --> Model ?
Great question, my answer = none
Did you choose the checkbox to "copy host cpu configuration"?
Great question, my answer = no

To setup nested KVM, I follow these instructions(https://pve.proxmox.com/wiki/Nested_Virtualization [1])
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
[2] Do we need this setting in the vm? _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users [3]
