Description Kevin Traynor 2019-03-01 15:57:59 UTC 
Qede pmd driver does not report the RTE_PCI_DRV_IOVA_AS_VA flag.

This means that access to /proc/self/pagemap is needed, however since Linux 4.x it is not allowed to non-root users without CAP_SYS_ADMIN privileges which openvswitch currently does not have.

TBC, this may be able to fixed by adding the flag to the Qede pmd similar to what is done in http://patchwork.dpdk.org/patch/50274/
Comment 1 Kevin Traynor 2019-03-01 16:09:46 UTC 
Rasesh, can you confirm that it is ok for Qede pmd to report this flag? If so, I can send a patch for it.
