venkataanil / ovn2.11 patching
Created November 16, 2019 02:57
Installing openvswitch (which requires wrappers as well)
note: "el7" are for RHEL7 and "el8" are for RHEL 8
1) download the below files to undercloud and then copy them to controllers
wget http://download-node-02.eng.bos.redhat.com/brewroot/packages/openvswitch2.11/2.11.0/26.el7fdp/x86_64/openvswitch2.11-2.11.0-26.el7fdp.x86_64.rpm
wget http://download-node-02.eng.bos.redhat.com/brewroot/packages/openvswitch2.11/2.11.0/26.el7fdp/x86_64/python-openvswitch2.11-2.11.0-26.el7fdp.x86_64.rpm
and the rhosp wrappers
wget http://brew-task-repos.usersys.redhat.com/repos/official/rhosp-openvswitch/2.11/0.6.el7ost/noarch/rhosp-openvswitch-2.11-0.6.el7ost.noarch.rpm
wget http://brew-task-repos.usersys.redhat.com/repos/official/rhosp-openvswitch/2.11/0.6.el7ost/noarch/python-rhosp-openvswitch-2.11-0.6.el7ost.noarch.rpm
2) login to nodes using "public ip i.e 10.x and not 192.x" as 192.x is on switch, which will break the connection when we install ovs
