Public bug reported:

Hi,
I am getting following error , when launching VM in openstack.
I am using devstack for compiling openstck.

following error is shown , when I try to launch VM.
"No valid host was found. There are not enough hosts available."

I am using ubuntu cloud image..
one VM instantiate successfully, but second image not able to launch, give above message.

first I thought, it can be issue of my system RAM. but System RAM (DELL
server) is 64 GB.

how to resolve this issue?

cirros images working fine (i tried launching 3 images, it works).
