that’s what the nested-vt hook does
again, with the current kernel it’s unlikely to work.
You can try Fedora, though we do not support running it for anything but 
development.

 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

 It's impossible, the second host is now - Hyper-V with working VM's.

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

Re: [ovirt-users] Turn on "Nested Virtualization" on the "hosted-engine"

[Martin Sivak]

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.

Best regards
