Bridged networking seems broken in my setup, while NAT does work.
During Debian install on the guest vm, I see that the installer identified the host's ethernet interface (visible in VBbox.log), but after a short while I get a message "Network autoconfiguration failed. Your network is probably not using the DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly" (I obviously have DHCP service on a healthy network)
I am not sure how to continue my troubleshooting. Any tips would be greatly appreciated.
My setup
- New Intel NUC 11 TNKi5 (with a 2.5Gbps Ethernet connection)
Host Ubuntu 20.04.2 LTS Server
Ubuntu Virtualbox distribution
Guest vm: Debien or Ubuntu server
