[ovirt-users] oVirt 4.2 alpha upgrade failed

[Maton, Brett]

It all got a bit messy, but that's probably down to me.

  I removed the 'old' ovirt repo definitions after I installed the 4.2 pre
release repo (simply because yum was complaining about multiple
definitions).

  I also allowed the installer to clean-up the old database directory,
which it did.
  The updated PostgreSQL server stayed up and running which stopped 4.1
from starting the version of PostgreSQL that it wanted running (port in use
I expect) etc etc etc

So no in this particular case roll back failed, but there are a bunch of
warnings issued but engine-setup that that would probably happen.

I've attached the engine-setup-log as requested.

Best regards,
Brett
