lost and found ( for me ? ): Ubuntu 16.04 uvt-kvm small tips : enable password authentication over SSH with root user

When creating a VM with uvt-kvm tool, the VM does not allow password authentication over SSH.

$ uvt-kvm create test01

$ uvt-kvm ip test01

192.168.122.22

$ ssh -l root 192.168.122.22

Please login as the user "ubuntu" rather than the user "root".

Here is how to enable password authentication with root user.

Prepare cloud-init file..

$ cat user-data

#cloud-config

ssh_pwauth: yes

chpasswd:

list: |

ubuntu:hello

root:hello

expire: False

runcmd:

- sed -i -e '/^PermitRootLogin/s/^.*$/PermitRootLogin yes/' /etc/ssh/sshd_config

- systemctl restart sshd

create a VM

$ uvt-kvm create --user-data=./user-data test02

$ ssh -l root `uvt-kvm ip test02`
