Hi again,
Here is some details about my lab test.
My physical machine is a Fedora 28, I have created on it two VMs, A manager
and Compute node using CentOS 7.5
The problem is as described previously, the vmlinuz does no get downloaded
using xnba or pxe.
I made another test, I used nested KVM to create a CentOS 7.5 hypervisor
then on top of it i created one Compute VM.
This time when using pxe, the vmlinuz get downloaded at 66% then it
freezes, but when using xnba the VM completely freeze and I get this error
on libvirt log
KVM internal error. Suberror: 1
emulation failure
