Hi friends,
I progressed in my installation, and now when I run 'nova-manage service list' I have all services with a ":-)" status even the additional compute node. But when I launch several instances, the ones hosted on the additional compute node, can't be launched, it gives me an ERROR status, herein the tails of log files (nova-compute.log, nova-network.log and libvirt.log) on the Cloud Controller:
