When I right click an empty host, and select upgrade and confirm
that I want to upgrade. It simply comes back with install failed after a
minute or two. I have no idea why its failing, there also does not
appear to be anything in /var/log/yum.log so I am not sure where else to
look to figure out why it cannot upgrade. Also to be clear, the wording
in Ovirt uses the term upgrade, however I am under the impression it
simply means update, not actually upgrade to 4.2.
Thank you all.
