Hi @olivierlambert, could you help me?
This is my config:

#cloud-config
hostname: netconf
#ssh_authorized_keys:
#  - ssh-rsa <myKey>
#packages:
#  - htop
users:
  - default
  - name: foobar
    gecos: Foo B. Bar
    primary_group: foobar
    groups: users
    selinux_user: staff_u
    ssh_import_id: foobar
    lock_passwd: false
    passwd: $6$eRE.alHl$1H0K9A4y66DM/aiQ9/9uUK2t3B89l/vidV47MQYVSNaWC1jFjJQRN72w3wSOmzz31X0R/ugr5pyhnkJ24NyCg/ #123

With or without it, I cant login in the console vm, the net config also doesn't work.
During the process I receive the message that could be the answer:

Have you seen this problem?
I have try the default config, but the user 'debain' with no password can't login too.
Thanks this is a greate tool!
