Did you manage to make it work with a static addressing network ?
I tried this (where myip and mygateway are replaced by real values)
network: version: 1 config: - type: physical name: eth0 subnets: - type: static address: myip/24 gateway: mygateway
with no success.
and as I don't have an IP assignated and theses cloud images are passwordless by default I can't event log in from the console to troubleshoot.
