Adding ovs 2.7.2 to our repo does not cause ovs 2.6 to be updated as 2.6 has epoch set to a higher value (Epoch 1) than 2.7.2 (Epoch 0). So even if we have 0:2.7.2 we are still installing 1:2.6.1. Reason for this is that openvswitch developers doesn't want to support "downgrade" from beta to non-beta. Some suggested solutions include modify engine-setup with something like: rpm -e 1:openvswitch-2.6 && yum install openvswitch if [ `rpm -q openvswtich` -eq 1:2.6 ] then pushd temp yum-download openvswtich rpm -U --force openvswtich.rpm popd done
RPM spec file behaviour is verified on: ovirt-provider-ovn-1.2.1-1.el7ev "Error: ovirt-provider-ovn conflicts with 1:openvswitch-2.6.1-3.git20161206.el7fdb.x86_64" "Error: ovirt-provider-ovn-driver conflicts with 1:openvswitch-2.6.1-3.git20161206.el7fdb.x86_64" Failed on doc text for workaround: Option 1: '--allowerasing' is not an option available on yum package manager that is used in RHEL. Option 2: if you download the RPM using yumdownloader and try to install it, yum will not install the package: # yum install openvswitch-2.7.2-10.git20170914.el7fdp.x86_64.rpm Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager This system is not registered with an entitlement server. You can use subscription-manager to register. Examining openvswitch-2.7.2-10.git20170914.el7fdp.x86_64.rpm: openvswitch-2.7.2-10.git20170914.el7fdp.x86_64 openvswitch-2.7.2-10.git20170914.el7fdp.x86_64.rpm: does not update installed package. Error: Nothing to do
Suggested doc text change (to perform a switch from epoch-1 to epoch-0): 1. Erase specifically the unwanted epoch-1 package: yum remove 1:openvswitch-2.6.1-3.git20161206.el7fdb.x86_64 2. Install the correct repository RPM, which supplies repository files for epoch-0. --- I'm not sure about a proper URL to supply here ? -- yum install <epoch_0_release.rpm> 3. Install the correct package using yum: yum install openvswitch-2.7.2-10.git20170914.el7fdp.x86_64.rpm This is checked and found to be working.
Dan, is that a blocker for 4.2.0?
Doctext updated
If you use yum directly, it will generate a WARNING message each time a user runs yum: "RPMDB altered outside of yum", and it will force the user to sync the DBs (and run additional command). What's wrong with just removing the improper packages and installing the correct ones using yum?

In case we prefer to leave the doc text as it is, I would add additional note that using 'rpm' directly might cause a WARNING in yum. To fix it, yum cache can be cleaned using 'yum clean all'.
