vmware ESXi in KVM

[Gunnar]

    I am trying to install esxi7 inside a KVM machine

    the installation process starts but does not get fails with a "No
    network adapters" error. This does not happen with other VM's.
    What do I have to add to above command in order to attach the
    default network adapter to the machine?
    
    or is there any other trick I have to be aware of when it comes to
    installing ESXi
    
    thx ... Gunnar
