I download the pre-build imalge for openstack on below page: https://openstack.redhat.com/Image_resources

    Specifically, I download this image: http://cloud.centos.org/centos/6/images/CentOS-6-x86_64-GenericCloud.qcow2

    But when I start new instance by using this image,  I dont know the default root password of this cloud image, any idea?

Best Regards,
