Description of problem
VPP integration as described in https://github.com/kata-containers/documentation/blob/master/use-cases/using-vpp-and-kata.md with current Kata versions results in the default ethernet device (eth0) have NOARP flag being set.
Hence, MAC addresses are not properly resolved.
Expected result
The containers should communicate using correct IP and MAC addresses.
Actual result
The containers do not resolve ARP addresses for the NOARP flag being set.
Root cause is the fact that the NOARP flag is automatically copied by kata-runtime from the ethernet device on the host, which is temporarily created by the docker plugin. As it happens to be a dummy device, it does have the NOARP flag set. An explicit configuration of the NOARP flag would resolve this issue.
Note: See #2187 for further issues with the setup.
