Seems I found the issue just for the case I mentioned in the last messages. I do not why but it seems the BMC tooks old settings. Bond was configured for the BMC and eth1 was activated. This causes issues if you use external NIC on B650. Now I can migrate the VMs without any issues again.

But all in all solves that issue but not the issue that other hosts reboots.
