Hi all, =20 As part of the upgrade process to 3.6 I will be rebuilding all hypervisors to CentOS7, and I'm starting with the Jenkins Datacenter. For this, I am evacuating slave VMs by shutting them down and restarting in the new cluster with CentOS hosts. =20 I'm currently working on ovirt-srv04 so please don't schedule any VMs on that host until it's rebuilt. =20 I found several VMs running on that host which are not listed on Jenkins so I can't mark them offline there for the update period: =20 fc21-vm01.phx.ovirt.org el6-vm06.phx.ovirt.org =20 If anyone knows what these VMs are used for - please tell me, otherwise I will just restart them as well. =20 Also this VM is present on this hypervisor: artifactory.phx.ovirt.org =20 Is it used by the slaves? Can it be shut down for a few minutes? I'm not sure I will be able to live migrate it even as the F20 hosts we have in the old cluster have issues with live migration even to other F20 hosts.

=20 Regards,=20 Evgheni Dereveanchin=20 =20 _______________________________________________ Infra mailing list Infra(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/infra

I'm back to the office and moving forward with the upgrade. Will now re-provision ovirt-srv01 which is part of the HostedEngine cluster and was the first host of the environment. Now backing up its configs just to be sure. There is 6 VMs still running on F20 hosts. Once there's two EL7 hosts in the cluster we will plan downtime and move them one by one just as we did with the other pre-prod ones.

Hi Eyal, Indeed, all hosts have to have 3.6 level packages installed before the engine gets upgraded. In this particular case we have some catching up to do on the host OS side of the infra. After host re-deploy is done we'll update VDSM and friends to 3.6, upgrade the Engine and change the compatibility level to make use of the new features.

Can you confirm the is the recommended upgrade flow to users as well?
