Hi All,

I am currently seeing this error on a dedicated compute node in my cluster. my controller and first compute node are working fine but I continue to see this exception on a second node I attempted to add to the cluster. I can see the hypervisor,nova-compute service, and linux bridge are all running and connected to controller but when I try to spawn an instance it fails with a similar message.

[UPDATE] I see the node in the compute service list but not the hypervisor list. I checked the libvirtd process and it's running okay

I tried renaming the node from 01 to 02 to see if the record was the problem but same exception:

I resolved it by uninstalling the compute service and manually typing the config. there must have been a mistake in my nova config file but it's working now.

i resolved it by rebooting the compute nodes after that the controller was online
