For oVirt 3.6.x, these are the rules: The ENGINE can be hosted on EL 6 or EL7 The HOSTS cannot be EL 6 -- must be EL 7+ or Fedora (I don't recall the version)
How to upgrade your hosts: * Put the oVirt EL 6 host into maintenance (that is, migrating or shutting down all GUESTS from that host) * Remove that Host from the cluster * Wipe and install EL 7 onto that physical machine * Bring that EL 7 machine into the cluster (via web gui Install) * Repeat for all of the rest of the EL 6 hosts to complete the upgrade to 3.6.x HOSTS on 3.5.x could either be EL 6 or EL 7, that is no longer the case with oVirt 3.6.x HTH On Fri, May 27, 2016 at 7:14 AM, Giulio D’Ippolito < [email protected]> wrote: > 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: > > > > > > > > > > > > > > *2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager > yumpackager.verbose:91 Yum queue package qemu-kvm-tools for > install2016-05-27 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager > yumpackager.verbose:91 Yum processing package > 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64 for install2016-05-27 > 09:46:50 DEBUG otopi.plugins.otopi.packagers.yumpackager > yumpackager.verbose:91 Yum package > 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64 queued2016-05-27 09:46:50 > DEBUG otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum > queue package vdsm for install/update2016-05-27 09:46:51 DEBUG > otopi.plugins.otopi.packagers.yumpackager yumpackager.verbose:91 Yum queue > package vdsm-cli for install/update2016-05-27 09:46:51 DEBUG otopi.context > context._executeMethod:142 Stage packages METHOD > otopi.plugins.ovirt_host_deploy.vdsmhooks.hooks.Plugin._packages2016-05-27 > 09:46:51 DEBUG otopi.context context._executeMethod:142 Stage packages > METHOD > otopi.plugins.ovirt_host_deploy.vmconsole.packages.Plugin._packages2016-05-27 > 09:46:51 DEBUG otopi.context context._executeMethod:148 condition > False2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 > Stage packages METHOD > otopi.plugins.otopi.packagers.dnfpackager.Plugin._packages2016-05-27 > 09:46:51 DEBUG otopi.context context._executeMethod:148 condition > False2016-05-27 09:46:51 DEBUG otopi.context context._executeMethod:142 > Stage packages METHOD > otopi.plugins.otopi.packagers.yumpackager.Plugin._packages2016-05-27 > 09:46:51 DEBUG otopi.plugins.otopi.packagers.yumpackager > yumpackager.verbose:91 Yum Building transaction2016-05-27 09:46:52 ERROR > otopi.plugins.otopi.packagers.yumpackager yumpackager.error:100 Yum > ['qemu-kvm-rhev-tools conflicts with > 2:qemu-kvm-tools-0.12.1.2-2.491.el6_8.1.x86_64']* > > 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 > > > > > > > > > _______________________________________________ > Users mailing list > [email protected] > http://lists.ovirt.org/mailman/listinfo/users > >
