Thanks Edger for your reply. I checked the host VM it has enough
resources to create tiny instances. I noticed there was no br-int
present on controller+compute node. I don't know why it was not
present. I manually created br-int and also set-manager to odl 6640
port. Then, I am able to create Nova instances.
I also noticed if re-started odl that ran in other VM, the controller
dashboard won't be able to create Nova instances again. it is the same
error. But at this time, br-int is present.
Thanks,
Irene

Review your nova-scheduler logs. It seems that yo have an issue
with the resources available to host VMs.

Also, you have to configure Devstack to send logs to files, otherwise
they are all in the screen windows.
I like this answer for more info on logging and Devstack.
