Appreciate it and thanks!
It required several installation attempts. There are definitely issues with the network stack. I'm using 802.3ad/lac, had vlan ids beyond 512. The connection was at least working in the setup partly. After the first boot of harvester there was no connection, the console spawning `ntdev vlans list size ([...]) > (512) max vport list size, some vlans will be dropped``.
This seems to me an issue with hardware offloading related to the system's Mellanox NICs. Regardless, the setup of harvester was still stuck after switching to vlan ids lower to 512.
