The dhclient lease looks ok. It has a largish MTU, but that should be fine.
Does the dhcp server in question require MAC based client identifiers? Could you please try: network: version: 2 renderer: networkd ethernets: all: match: name: ens* dhcp4: yes dhcp-identifier: mac Note the additional 'dhcp-identifier: mac' key. Failing that, a package capture using wireshark inside the guest would be needed; under systemd-networkd, and again under dhclient. Packet capture should reveal what sort of things systemd-networkd is doing different to dhclient. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779721 Title: systemd-networkd does not configure DHCPv4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1779721/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
