Matthias,

These steps, "install python-nova", "install openstack-nova-scheduler" need python-openvswitch-2.11 which in turn looking for libopenvswitch which is provided by openvswitch-1:2.12.0-1.el7.x86_64.rpm. And I have this copy installed on my local repo.

Trying to figure out which rpm has the librte_*.

BTW, I got most rpms from http://mirror.centos.org/centos/7/cloud/x86_64/. Which has rpms for train, stein, rocky and queens.

Is there a similar site for later releases like Ussuri or Victoria?

Pete

Packages ending with el7 are probably a bit aged already. You may want
to switch to something more recent. RDO is only updating the latest
release.
I don't know where you got the other packages from, but I can see there
is no direct dependency from openstack-nova-scheduler to
openvswitch[1]. On the other side, the openvswitch build indeed requires
librte[2].

RDO describes the used repositories[3], and you may want to enable
CentOS extras.
