When a 'cont' is issued on a VM that's just waiting for an incoming migration, the VM reboots and boots into the guest, possibly corrupting its storage since it could be shared with another VM running elsewhere. Ensure that a VM started with '-incoming' is only run when an incoming migration successfully completes. A new qerror, QERR_MIGRATION_EXPECTED, is added to signal that 'cont' failed due to no incoming migration has been attempted yet.
