I am trying to migrate (Static migrate) an instance from one compute host to another by running the command “nova migrate” but it results in the vm going in error state.

Error:

Command: ssh 10.10.10.31 mkdir -p /var/lib/nova/instances/9edcde17-38db-4f80-94e7-fb60bf5c55a0 u'ssh: connect to host 10.10.10.31 port 22: Connection refused "message": "Unexpected error while running command.

Please provide information on what could be the reason for this as all the services are up and running.

Moreover, when i am running comand neutron agent list then i am unable to see new compute host over there.
