ok two things here:

* this ova is malformed it seems, it has a HostResource of '/disk/vmidsk1' when
the spec says it should be of the form 'ovf:/disk/vmdisk1' which is what we look for
(we could make that optional though?)

* seemingly live-import does not start the vm if there was no disk, but AFAICS
this was pre-existing and not something my series introduced (but not sure either)
