Yep, there's a design bug in the way this is implemented in the QEMU driver.
The code that restores the snapshot is in the qemudDomainStart() method,
rather than qemudStartVMDaemon(). This means that when the guest is
autostarted, the snapshot restore is missed.
btw, there's another bug in the managedsave function I think: it doesn't
honor the save_image_format directive in qemu.conf
