Open Stack

Hi,

I launch the openstack by running stack.sh as mentioned in 
http://devstack.org/guides/single-machine.html

I created some images and instances in devstack using dashboard. When I 
reboot Host machine and run stack.sh again, those images and instance got 
lost, and I am not able to see those images and instances that I already 
created using dashboard.

My question is

1. Is this what is expected from host reboot?
2. What I need to do to retain images and instances between multiple host 
reboots.

The thread 
http://www.mail-archive.com/openstack@lists.launchpad.net/msg08453.html 
says to use the switch  --start_guests_on_host_boot 
--resume_guests_state_on_host_boot. I am not sure how I should use these , 
which config files should have those switched enabled when I launch the 
devstack by simply running stack.sh 

I guess I need to pass some parameters or need to  do **something** before 
running to stack.sh so that it does not destroy already crested instances 
and images. As I understand stack.sh  reinitialize  all the stuffs

Looking for any help.
