I'm afraid this won't work, we changed so many things in the packaging/setup between 3.0 and 3.1

the "sane" upgrade path (nothing is sane in Fedora 16 to Fedora 17 upgrade):
1. run engine-cleanup, do not drop DB
2. remove all ovirt-engine rpms (including the JBoss one)
  - please not that this will remove the PKI, so you'll have to re-install your hosts
3. Do the fedora upgrade
4. install ovirt-engine rpms
5. run engine-setup
  - Give same passwords to the DB/admin user

in this case, engine-setup should upgrade the db, and not install it.
we didn't tried this approach yet, so I'll appreciate any input.
