I have installed devstack on ubuntu 14.04 and have rebooted Virtual Machine, but after reboot openstack is not working and getting the following errors:

Overview -> Error: Unable to retrieve usage information
Instances -> Error: Unable to retrieve instances.
Volumes -> Error: Unable to retrieve snapshot list.
Images -> Error: Unable to retrieve images.

As I have found the solution on stack overflow, there is no ./rejoin-stack to retain all the Virtual Machines So I am trying to execute the command inside devstack directory i.e.

cd devstack
$devstack screen -c stack-screenrc

By running above command, I found that Virtual machine network interfaces are automatically created and by this the physical wired connection is getting disconnected. I have attached the screen shot of network interfaces created.

enter image description here

Can anyone help me please, Thanks

Any inputs??

  • After rebooting the machine, did you run the stack.sh again? – Ankur Bhatia Oct 27 '16 at 11:53

    No, If we run ./stack.sh, it will erase all the data. I can't retrieve the data. So I am trying to retrieve the data for that I ran the command "screen -c stack-screenrc ". Thanks – Anusha P J Oct 28 '16 at 07:05
