[ovirt-users] Problem upgrading Host from 3.5 to 3.6 in Centos 6

[Giulio D’Ippolito]

Hi all,

We are having a bit of hard time trying to upgrade oVirt from 3.5 release
to 3.6.

This is our setup:

   - All the hosts are running Centos 6.7
   - The engine is a standalone machine
   - The engine is running Centos 6.7
   - Upgrading the engine from 3.5.x to 3.6.6 was successful

Now the problem was when we were trying to upgrade the hosts to 3.6
release.

We put one host in maintenance and we were expecting the "Upgrade" option
to be available but it wasn't.

We have imported the 3.6 repository to the host and performed a "yum clean
all" and a "yum update" to see which packages were marked to be upgrade.

No packages in the oVirt 3.6 repository were available to upgrade.

Then we tried to use the "Reinstall" option available in the GUI

The reinstall failed with the following issue:

We fixed the issue via removing the qemu-kvm-tools and running the
"Reinstall again".

But effectively this was the only package that was installed/upgrade by
running "Reinstall" again.

I can see from the repository
http://resources.ovirt.org/pub/ovirt-3.6/rpm/el6/x86_64/ that not many
packages are available in this repository for Centos 6.

For example vdsm package is still version vdsm-4.16.30-0.el6 which was
installed in oVirt 3.5

Is this the expected outcome of the upgrade in the host?

Thanks,

Giulio
