Hi All, As a project requirement , i have to use openvswitch v2.9.2 .

My scenario: two node setup: host1(controller+network), host2(compute)

When i am installing the nova service , neutron service it automatically installing openvswitch v2.11 as a dependancy along with others like libopenvswitch ,python-openvswitch .

With my project changes i have created the rpm of the v2.9.2 and started running as a service and later on when i install above mentioned services its removing v2.9.2 ovs and installing latest v2.11 ovs.

So how do i need to proceed to make use of v2.9.2? Do i need to change to some older openstack version ? Which openstack version will be supported to use ovs 2.9.2 ?

Please help me on this..working on this issue since 2 weeks but i didn't found the alternative.

Thanks, Vill.

There is an old spec, which was implemented some five years ago, for not checking Openvswitch versions anymore. This means that Neutron doesn't know which version is required.

Strictly speaking, therefore, it is not Neutron but the Neutron package on your OS (RHEL, Centos, OpenSUSE?) that automatically installs version 2.11 of openvswitch. i suggest you configure your package management system not to do that, install version 2.9.2 and try it out.

It seems you can configure yum to exclude packages, though I have never tried it. A search for yum excludeyields a few promising web pages such as https://www.tecmint.com/yum-lock-disa....
