[ovirt-users] oVirt 4.2 upgrade procedure.

[Eduardo Mayoral]

Thank you for the explanation. My misunderstanding, then. It seems that
I could get away with only including centos-release-ovirt41 in the past,
but not any more.

Once I did that I was *almost* able to upgrade some of the hosts (I will
do the rest later).



Warnings for others:

I had a custom /etc/multipath.conf , since it started with the line "#
VDSM REVISION 1.3" , vdsm refused to start (There was a clear warning of
this in /var/log/messages). Once I changed the first 2 lines to:

# VDSM REVISION 1.4
# VDSM PRIVATE

Everything was fine.


I cannot update userspace-rcu.x86_64 from 0.7 to 0.10 because of this
bug. https://bugzilla.redhat.com/show_bug.cgi?id=1507090  No big deal
for me since I am not using gluster, but I guess that basically
everybody will be getting the same.

All my hosts show a warning in the general tab in the UI with an
exclamation icon and the text "Host has no default route". I indeed have
a valid default gateway on the management interface for all my compute
hosts.

I like the new UI.

Thanks for your help!
