Hi,
it might be a good idea to install vdsm-hooks-nestedvt and vdsm-hook-macspoof on the host as described for example here: https://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/
Those two hooks will configure the kvm module properly and allow dhcp/pxe to be used from within the nested VM.
Yes. Though it’s likely not going to work out of the box anyway due to older kernel. See a guide from Ladi[1], there was also a presentation about nested hyper-v on KVMForum 2017
Thanks, michal

the layering: oVirt host -> Hyper-V_VM on oVirt -> VM on Hyper-V_VM
CentOS based on linux kernel. I manual modified linux kernel parametrs.
if you modified the kernel parameters already (which you did, as seen in screen shot your cmdline does have nested virt param) then there’s nothing else to do in the GUI, your host should support nested virtualization. I’m not sure why do you need SR-IOV but that’s not going to work on top of hyperv
oVirt-engine based on oVirt API. How to manually change the parameters of ovirt-engine through API?
In any case, I assume an additional host is needed, the host hosting the Hosted-Engine VM cannot be changed with those parameters when the HE is up. Y.
It's impossible, the second host is now - Hyper-V with working VM's.

Thanks for the quick response.
You probably need an additional host.
I'm migrating from Hyper-V at the moment there is no way to add a second host.

"Nested Virtualization" . I need run on Hyper-V one VM on the my oVirt
