Hi, i tried to upgrade my oVirt 4.1.9 test environment to version 4.2.2. this failed on the engine host with messages like 2018-04-23 11:10:57,716+0200 ERROR otopi.plugins.otopi.packagers.yumpackager yumpackager.error:85 Yum Test-Transaktionsfehler: file /usr/share/ansible/roles/ovirt-manageiq from install of ovirt-ansible-roles-1.0.4-1.el7.centos.noarch conflicts with file from package ovirt-ansible-manageiq-1.1.6-1.el7.centos.noarch file /usr/share/ansible/roles/ovirt-image-template from install of ovirt-ansible-roles-1.0.4-1.el7.centos.noarch conflicts with file from package ovirt-ansible-image-template-1.1.5-1.el7.centos.noarch file /usr/share/ansible/roles/ovirt-infra from install of ovirt-ansible-roles-1.0.4-1.el7.centos.noarch conflicts with file from package ovirt-ansible-infra-1.1.4-1.el7.centos.noarch file /usr/share/ansible/roles/ovirt-vm-infra from install of ovirt-ansible-roles-1.0.4-1.el7.centos.noarch conflicts with file from package ovirt-ansible-vm-infra-1.1.5-1.el7.centos.noarch file /usr/share/ansible/roles/ovirt-cluster-upgrade from install of ovirt-ansible-roles-1.0.4-1.el7.centos.noarch conflicts with file from package ovirt-ansible-cluster-upgrade-1.1.6-1.el7.centos.noarch i'm attaching the setup log file. fact is that the engine host CentOS 7.4 OS hasn't been updated for a while before the oVirt upgrade, i wanted to do that after successful oVirt upgrade. this seems to have played a role in failure to start the openvswitch service which happened before the final failure (seems to be a problem of SELinux policy) engine host OS configuration is roughly: kernel: 3.10.0-693.17.1.el7.x86_64 SELinux policy: 3.13.1-166.el7_4.7.noarch repolist: centos-opstools-release/x86_64 centos-sclo-rh-release/x86_64 centos7-x86_64 centos7-x86_64-extras centos7-x86_64-sclo-rh centos7-x86_64-updates ovirt-4.1/7 ovirt-4.1-centos-gluster38/x86_64 ovirt-4.1-centos-qemu-ev/x86_64 ovirt-4.1-epel/x86_64 ovirt-4.1-patternfly1-noarch-epel/x86_64 ovirt-4.2/7 ovirt-4.2-centos-gluster312/x86_64 ovirt-4.2-centos-opstools/x86_64 ovirt-4.2-centos-ovirt42/x86_64 ovirt-4.2-centos-qemu-ev/x86_64 ovirt-4.2-epel/x86_64 ovirt-4.2-virtio-win-latest ovirt-centos-ovirt41/x86_64 sac-gdeploy/x86_64 virtio-win-stable the host that is the engine is a VMware VM (no self hosted engine setup) thanks for any help -- Matthias Leopold IT Systems & Communications Medizinische Universität Wien Spitalgasse 23 / BT 88 /Ebene 00 A-1090 Wien Tel: +43 1 40160-21241 Fax: +43 1 40160-921200
