The name of the file should correspond to the port name, so it should just be /var/openvswitch/dpdkvhost0. Check this directory to confirm.

Do you see either of the following logs?: INFO|vHost Device '/var/run/openvswitch/dpdkvhost0' 0 has been added INFO|vHost Device '/var/run/openvswitch/dpdkvhost0' can't be added - name not found Thanks, Ciara > > > > > From: ciara.lof...@intel.com > > To: haristan...@hotmail.com > > CC: discuss@openvswitch.org > > Subject: RE: [ovs-discuss] dpdk vhostuser port not working > > Date: Wed, 25 Nov 2015 10:29:24 +0000 > > > > > Hi, > > > I am using ovs 2.4.0.
