Hi, TL;DR How to get systemd-nspawn containers networking so that they can talk to each other, the host and the internet inside a Buster VM? VirtualBox on Windows 10 which has internet connectivity via a wireless interface.
I am running a Buster VM with hand picked minimal packages, networking is configured simply using interfaces(5) file with DHCP. I have configured a "NatNetwork" on VirtualBox which allows the VMs to connect to each other and the internet. I was wondering if I can do similar thing with containers inside the buster VM. I used `debbootstrap' to have a template directory of buster under "/opt/templates/buster". I then simply copy the directory tree over to "/var/lib/machines". I tried a few networking options of `systemd-nspawn', but since I am not well educated about macvlan, ipvlan, I could not get the networking working at all. I would like to avoid using "systemd-networkd/systemd-resolvd" especially on the Buster host - using those it seems should make everything work automagically. If it works then I will be able to test my Dovecot/Exim setup easily in such throwaway containers. I currently do testing using VMs. Does anyone have experience in having this kind of scenario working? Regards, Didar -- Baby On Board.
