Hi, upgrade from FC20 to FC22 has not been tested and you're welcome to
help testing it.
What I would suggest is:
- make an image of your existing engine (I suggest clonezilla for doing it)
- install ovirt-release36 from
http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm
- fedup from fc20 to fc22 directly, without the fc21 step
- run rpmconf -a and update relevant config files (be sure to not just
overwrite them!)
- run postgresql-setup --upgrade
- run engine-setup

I suggest to update to fc22 directly because there aren't FC21 builds of
ovirt engine and the fedup process may not work as expected with missing
repos.

If the upgrade fails, you can restore the disk image created with
clonezilla and retry with a different procedure.

If you hit any issue or if you succeed let us know!
