Hi, I just started upgrading one of our oVirt installations from 4.1.8 to 4.2 Engine is NOT self hosted. It is a plain CentOS 7.4 server. Compute hosts (10 of them) are CentOS 7.4 as well. Storage is mainly iSCSI served from an external storage system. Engine upgrade was seamless. Now I want to upgrade the hosts, then change the cluster compatibility level, then the datacenter compatibility. Can someone confirm that this is the correct sequence? On the first host, I put it in maintenance mode, installed centos-release-ovirt42 and removed centos-release-ovirt41. When doing the upgrade host from the web interface, I get: 2017-12-28 10:58:46,054 p=7173 u=ovirt | Using /usr/share/ovirt-engine/playbooks/ansible.cfg as config file 2017-12-28 10:58:46,288 p=7173 u=ovirt | PLAY [all] ********************************************************************* 2017-12-28 10:58:46,316 p=7173 u=ovirt | TASK [ovirt-host-upgrade : Install ovirt-host package if it isn't installed] *** 2017-12-28 10:58:51,143 p=7173 u=ovirt | fatal: [llki612.arsyslan.es]: FAILED! => {"changed": false, "msg": "No package matching 'ovirt-host' found available, installed or updated", "rc": 126, "results": ["No package matching 'ovirt-host' found available, installed or updated"]} 2017-12-28 10:58:51,144 p=7173 u=ovirt | PLAY RECAP ********************************************************************* 2017-12-28 10:58:51,144 p=7173 u=ovirt | llki612.arsyslan.es : ok=0 changed=0 unreachable=0 failed=1 Now, I see the ovirt-host package is not installed or available on the Compute node. It is available on the ovirt-engine on repo "ovirt-4.2" (which is installed by ovirt-release42-4.2.0-1.el7.centos.noarch) I am a bit confused here. I thought I only needed centos-release-ovirt42 (centos-ovirt42 repo) on the compute hosts. Is that so? Has this changed from 4.1 to 4.2?

Where did you find instructions to install centos-release-ovirt42? Generally speaking, oVirt repos are available by installing ovirt-release*.
