Closing this as Invalid as this appears to be an incorrect use of the multi host mode in nova-network. That is, the network has been configured as multi host but the deployment isn't running nova-network on every compute host.
The newest documentation (Grizzly) about the nova-network multi host feature I could find says: "The multi_host option must be in place when you create the network and nova-network must be run on every compute host. These created multi hosts networks will send all network related commands to the host that the specific VM is on."

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1297642 Title: Evacuate fails during rebuild of the VM on the target host with RPC timeout Status in OpenStack Compute (Nova): Invalid Bug description: when using the 'nova evacuate' to evacuate a VM with no shared storage to a target host the command fails during the rebuild step leaving the VM in the rebuilding state on the target host. The VM is evacuated from the failed host but fails with RPC timeout error during the rebuild on the target host. Here are steps to recreate the issue: 1) create a vm on a host nova boot --flavor m1.small --image my_image test-vm 2) disable the compute host of the VM and stop the nova-compute process on it 3) nova evacuate test-vm target-host the VM is evacuated from the failed host and starts rebuilding on the target host | 5) check test-vm nova show test-vm server error 500 with roc timeout and the VM is suck in the rebuilding state on the target host.
