There has been significant changes to the code. Please try again and reopen the bug if the issue continues to exist.

This happens when u do not start Kuryr service with enough privilege.

Kuryr needs higher privilege to create local veth pair.

I will try to see if we can make some workaround.

    Add "sudo" to the instruction for running Kuryr

    This patch adds "sudo" to "Running Kuryr" section of README.rst. Some
    people get stuck with the errors of pyroute2 and that's because of the
    lack of the privilege for manipulating the veth interfaces.
