Public bug reported:

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.
