Title:
  InvalidCPUInfo exception not catched in conductor _live_migrate

Status in OpenStack Compute (Nova):
  Fix Committed
Status in OpenStack Compute (nova) icehouse series:
  In Progress

Bug description:
  Environment: 
  - fresh devstack multinode installation using nova-network.
  - one controller node with a compute node (node_1) 
  - one compute node (node_2)

  Both compute nodes has different cpu info features.

  When live migrating from node_1 to node_2 an InvalidCPUInfo is raised in live_mirgate method in conductor's manager.
  The exception is not captured and the roll back of the task_state is not performed. 
  The instance stays in 'migrating' state.
