QEMU 4.1 and network

[Frans de Boer]

LS,

I was trying to use qemu 4.1. under opensuse tumbleweed, had compiled it 
myself for opensuse 15.1, but none is able to get a network connection.
When I switched back to qemu 3.1.1, there is no problem.

I tried various settings like '-net nic.....', '-nic tap....' and even 
'-netdev  ..', to o avail.
What has changed so drastically that qemu is not getting a IP-address 
anymore?
