You can check if openstack-nova-network running on the controller - but if you are using multi-host networking this is probably irrelevant. IIRC, if you are using multi-host networks you need to keep in mind that while each compute node is a network controller - the reverse is also true. i.e. a node is only a network controller for an instance's tenant network IF that node has an instance for that tenant running on it. If there isn't an instance for a particular tenant on a given node, there may be no bridge for that tenant network, etc. on it. This has to do with how the networks are provisioned - the bridges are setup where a tenant network is required, i.e. where an instance has been booted. Also of course, there is no standalone network-controller. To get access to your guest, try going through the multi-host node instead of the "controller" (which isn't a network controller in this case). If you *don't* use multi-host then you the network service should only be required on one host. Cheers, Brent
