No free nbd device available

asked 2016-07-07 21:43:39 -0500

I am not able to run the multiple instances at openstack. I was successful in launching Cirros Os on my openstack and now when I am trying to run the next instance of Ubuntu, its unsuccessful. I checked var/logs/compute.log and it says no free nbd device available and then threw error with no disk allocated.

Please let me know how to solve this issue
