Just to document it and keep history.
I solved the problem by updating the kernel and libvirt.
Kernel-4.x and libvirt-8.x do not correctly detect processors from the
cascadelake family.
If you have 2 physical sockets on the host, the combination of kernel and
libvirt above will only detect 1

Sorry, I mentioned it wrong. The engine VM is ok. What happens is that the
lscpu output of the physical host is different from the host information

Mencionei errado, não me refiro à VM da engine, me refiro ao oVirt como um
todo.
No host mostra apenas 1 socket.

Jorge,
Your 8276 processor belongs to the former Cascade Lake Family (server), which
is supported by oVirt (listed as Intel Cascadelake Server Family).
For CPU requirements see:
Olá Jorge
Se foi alocado apenas um socket a vm hosted engine, ela verá exatamente
essa configuração.
