Glad that helped. I'm confused as to why cloud-init doesn't add the mac addresses - it does in my VMs. Let's ask them; I'll add them to the bug.
** Description changed: + == cloud-init query == + + Cloud-init isn't adding MAC addresses in the match stanza for various + network interfaces in /etc/netplan/50-cloud-init.yaml, which is leading + to unexpected results. Is there any reason this would happen? + + + == Original Description == + Running nplan 0.30 on Ubuntu 17.10. From what I can tell, the ethernets/interface/mtu field isn't applied when testing against a private ethernet adapter. Using a netplan yaml file (/etc/netplan/10-ens7.yaml): --- network: - version: 2 - renderer: networkd - ethernets: - ens7: - mtu: 1450 - dhcp4: no - addresses: [10.99.0.13/16] + version: 2 + renderer: networkd + ethernets: + ens7: + mtu: 1450 + dhcp4: no + addresses: [10.99.0.13/16] --- Then running "netplan apply" (or rebooting), yields the following: --- 6: ens7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 - link/ether 52:54:00:2a:19:bc brd ff:ff:ff:ff:ff:ff - inet 10.99.0.13/16 brd 10.99.255.255 scope global ens7 - valid_lft forever preferred_lft forever - inet6 fe80::5054:ff:fe2a:19bc/64 scope link - valid_lft forever preferred_lft forever + link/ether 52:54:00:2a:19:bc brd ff:ff:ff:ff:ff:ff + inet 10.99.0.13/16 brd 10.99.255.255 scope global ens7 + valid_lft forever preferred_lft forever + inet6 fe80::5054:ff:fe2a:19bc/64 scope link + valid_lft forever preferred_lft forever --- Is this a bug in netplan, or am I misunderstanding the YAML syntax?
