OpenStack Create mirror build virtual machine don't know how to solve the password

Background:

OpenStack Juno version, use Glance to create a centos7 mirror, and then build the virtual machine.

Operation Steps:

First get the mirror Http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1503.qcow2

Wget-p/tmp/images Http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1503.qcow2

Create Mirror Glance image-create--name "cirros-0.3.3-x86_64"--file/tmp/images/centos-7-x86_64-genericcloud-1503.qcow2-- Disk-format qcow2--container-format Bare--is-public

True--progress

Then create the virtual machine on the dashboard, but I don't know the root login password after using this image to create the virtual machine.

The final solution is to execute a password change step when creating the virtual machine.

Then log in to the virtual machine and you're ready.
