I do not think I understand the question.

Migration from standalone to hosted-engine does not involve a nic
in an ovf, AFAIU.

To get/set stuff on the shared storage, hosted-engine has options
'--{get,set}-shared-config', see also:

https://bugzilla.redhat.com/show_bug.cgi?id=1301681

For the engine vm.conf, indeed it's updated from data in the engine
db, but I do not know well the details. Adding Simone.
