Public bug reported:

When testing block live migration, a KeyError exception was thrown in
post_live_migration in nova/virt/libvirt/driver.py on the origin host
after the VM was migrated to the destination host.

This is because connection_info['data'] doesn’t have a key called
‘devices’ in disconnect_volume of LibvirtFibreChannelVolumeDriver.

nova/virt/libvirt/volume.py
class LibvirtFibreChannelVolumeDriver
    def disconnect_volume(self, connection_info, mount_device):
        """Detach the volume from instance_name."""
        super(LibvirtFibreChannelVolumeDriver,
              self).disconnect_volume(connection_info, mount_device)
        devices = connection_info['data']['devices']

The FC driver I'm testing with is the EMC SMI-S FC driver.

This problem is similar to https://bugs.launchpad.net/nova/+bug/1222979.
