The agent expects a IP CIDR for the route destination rather than an IP address. netmon was incorrectly converting route dest to an IP address and hence exiting with an error. We did not have an integration test for netmon with tcfilter mode. macvtap mode did not uncover this, as with macvtap routes are not really passed to the agent. We delete the IP on the veth device, and netmon looks at the routes after the IP is deleted with macvtap. Fixes kata-containers#1523 Signed-off-by: Archana Shinde <[email protected]>
