Open Stack

I find error message “ComputeHostNotFound: Compute host 2 could not be found.” in compute.log
Can you restart your nova-compute process and try again?
More log info is better

主题: [Openstack] Error while creating a Nova instance

Hello All,

I’ve installed OS Havana on my servers and while trying to launch an instance it fails immediately and shows the instance state as ERROR

My setup is

MySQL/QPIDD/Horizon/Nova controller/Glance running on a single server (8GB RAM/4vCPU) and Nova compute on a different server(32GB RAM/8CPU)

/var/log/nova/compute.log has the following error trace while I create an instance : http://paste.openstack.org/show/53590/

Whenever I trigger a launch request it fails and this is the status of my server
