qemudStartVMDaemon is called during migration (and restore), but it does not sent "cont".
The only place where "cont" is sent where passphrase handling is not necessary is qemudDomainResume. In any case, the passphrase handling only does something if qemu prompts for a passphrase, it does not hurt anything in other cases - on the contrary, should something go wrong and qemu would prompt for a passphrase, this ensures libvirt either supplies a passphrase, or reports an error, instead of hanging.
