packstack --all-in-one not generating keystone_admin file

Hi Community,
I am trying to deploy openstack 7.0 eval edition. Issue is, the system is not able to generate keystonerc_admin file however, it says that it generated one towards the end of installing components. I am not finding anything under /root or /testdir(root user's home directory).

Additional information after running command packstack --allinone

• Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
• File /testdir/keystonerc_admin has been created on OpenStack client host . To use the command line tools you need to source the file.
• Copy of keystonerc_admin file has been created for non-root user in /root.
• To access the OpenStack Dashboard browse to http://192.169.2.151/dashboard .
  Please, find your login credentials stored in the keystonerc_admin in your home directory.

Thanks,
Vijay
