Just to summarize and put this all in one place:

There are 2 general methods for upgrading an ovirt-node installation.

1.  Through oVirt Engine
2.  Through oVirt Node installation media (ISO, CD, USB, PXE)

#1 is done by installing the ovirt-node-iso rpm on oVirt Engine.  A node
is then placed in maintenance mode, and you trigger the upgrade from the
engine interface.

#2 is done using installation media.  Simply boot your host running an
old version of node from new media.  Either PXE, CDROM, USB, SD card,
ISO, etc. are supported.  Once you boot from the media, it will bring
you to a TUI screen where you choose upgrade.  That will upgrade and
leave existing configuration in place.

There are some other options as well, but they're in a slightly
different, but related, category.

Reinstall:

This will wipe out any existing configuration and install from scratch
This is done either by choosing the "Reinstall" option in the Boot menus
(with CD/USB/SD Card) or adding "reinstall" to the kernel command line
(any method).

Uninstall:

This will wipe the ovirt-node-iso installation from the disk entirely
and reboot.  
Again, there is a "Uninstall" option in the boot menu.  You can also add
"uninstall" to the kernel command line.
