There's no corresponding virDomainRestore, but "virsh start $vmname"
works: it starts the machine from the snapshot. Instead of being NULL,
the pointer to virDomainRestore should be initialized with the
function that is called for "start".

Your very right! As of now:
* virDomainRestore works only on three out of 6 hypervisors.
* virDomainSave is implemented on 4/6, but vbox's implementation is
not conformant and lacks a corresponding restore.



Until a better API is defined in libvirt and/or virtualbox, would you
be interested in a patch that would tread the filename for the
snapshot as a name and which would enable restore support as I
described in https://www.redhat.com/archives/libvir-list/2009-August/msg00185.html
?
