But we didn't expose this status to user, instead we returned the 'active' state. Here, we expose it to the user (such as libvirt), 'cancelling' status only occurs for a short window before the migration aborts, so for users, if they cancel a migration process, it will observe 'cancelling' status occasionally. Testing revealed that with older libvirt (anything 1.2.13 or less) will print an odd error message if the state is seen, but that the migration is still properly cancelled. Newer libvirt will be patched to recognize the new state without the odd error message.
