The default user is ubuntu. Password for this user must be specified while deploying process. For example for VMware player deployment process: Setting password for a default user

    Sure, as I said created VM with VMWare and provide a password on VM creation step. After this login in shell with user ubuntu and password.

you can create a new user or change passwd in grub Recovery Mode.

  1. holding shift key for grub menu when booting virtualbox vm

  2. select Advanced -> recovery mode, then select root and press enter

  3. passwd or add user:

    adduser <username>
    usermod -aG sudo <username>

Default password as ubuntu worked for me.


Ubuntu cloud images require cloud-init functionality to create loginable users (and whatever else needs to be done on boot). it sounds like vmware abstracts cloud-init away, and wraps it in vmware a "set user password" gui function, for ease of end-user. i have not tried specifing cloud-init, other than ec2, but sounds like cloud-init user solution would resolve this issue, for any virtualization that supports cloud-init (vmware, openstack, etc)


If you came here after a very long search trying to get Ubuntu cloud image working on Virt-manager, because you cant login see here. It includes how to specify the password which is generated by cloud-init: What are the different versions available as Ubuntu cloud-images?
