Official openvswitch package for CentOS7
by C. L. Martinez 21 Sep '15

21 Sep '15

Hi all, Exists an official openvswitch package for CentoS7?? If I am not wrong, this: http://mirror.centos.org/centos/7/cloud/x86_64/openstack-kilo/openstack-neu… it can be used with openstack only. Do I need to recompile from source like is is explained here: https://n40lab.wordpress.com/2015/06/28/centos-7-installing-openvswitch-2-3… or exists another rpm package for CentOS7?? Thanks.

If not, there definitely should be. :-) I'm actually not working today -- Sandro and Alan, let's sync up over e-mail on Monday (and/or at the Virt SIG meeting on IRC on Tuesday). -George
