Login via console to your failed openstack deployment
This is a copy of a blog that I wrote where I work at Octopus Computer Solutions
While installing Redhat Openstack on Baremetal with lots of complicated networking, you might need to access Linux via the console. Redhat images do not come with a default username and password. So you need to configure the overcloud-full image to have a default password for root.
$ sudo yum install libguestfs-tools
$ source ./stackrc
$ virt-customize -a overcloud-full.qcow2 --root-password password:YOUR-SECURE-PASSWORD
$ openstack overcloud image upload --update-existing
This will install and set the root password, then upload it to the undercloud Glance. This is the simplest way to update the password.
Octopus Computer Solutions is a Red Hat business partner. We deploy OpenStack and OpenShift throughout Israel. We have encountered customers which wanted to have an image of the OpenStack host with a customized password. This is a small How-To on how to do it.
