failed to start instance (Missing source '/dev/null' for disk 'aadisable') #110
Description
When deploying the "canonical-kubernetes" spell on an Ubuntu 17.04 system and LXC 2.1, Juju machines get in failed state with the following error:
Machine State DNS Inst id Series AZ Message
0 down pending xenial failed to start instance (Missing source '/dev/null' for disk 'aadisable'), retrying in 10s (3 more attempts)
The only workaround I found, which I'm not sure if it yields a working k8s cluster or not, consists of changing the lxd-profile.yaml file and removing the entire "devices" section (for aadisable and aadisable1).
