Hello, I believe the root password is disabled (also SSH password s). What you can do is boot in single user (init=/bin/sh) and unlock the password, set a custom password etc This attaches your configuration as a virtual CD-ROM device, which cloud-init will use rather than the network metadata service. If I put your cloud-config into a file called user-data.yaml, and then run: nova boot --image centos-7-cloud --user-data user-data.yaml centos. Then I can log in as the centos user using the password stackops 7 The default username for the CentOS 7 cloud image is centos. There is no password; instead you log in with the ssh key you provided at instance creation. You can then sudo and do whatever you like I recently installed OpenStack Mitaka on my test bed and imported few images from CentOS & Ubuntu repositories. Once the VM is booted, I tried to through VNC console. Unfortunately, I didn't knew the username and password and the information was not available on the page where the image was downloaded as well
