The kernel built with this packages does have VXLAN compiled.
It would be nice if this could be fixed since VXLAN is used Flannel and maybe other CNI plugins for Kubernetes.
$ grep -i vxlan /boot/config-4.4.0-1039-kvm
# CONFIG_VXLAN is not set |

== SRU Justification ==
VXLAN is used by Flannel and maybe other CNI plugins for Kubernetes,
it will be great to enable the support in KVM kernels.
== Fix ==
Enable the CONFIG_VXLAN in the config file.
CONFIG_NET_UDP_TUNNEL=m and other configs were added automatically with
updateconfigs.
CONFIG_OPENVSWITCH_VXLAN supprt was excluded intentionally as this is
not requested (and to reduce the binary size).
== Test ==
Test kernels could be found here:
https://people.canonical.com/~phlin/kernel/lp-1811819-vxlan/
Kernel smoke tested.
User has also verified that all the patched kernels are working as
expected.
== Regression Potentail ==
Low, this enables the support for VXLAN module on KVM kernels, we might
see some related bugs in the future. Since we already have this in the
generic kernel so the impact should be small.
== Original Bug Report ==
The kernel built with this packages does have VXLAN compiled.
It would be nice if this could be fixed since VXLAN is used by Flannel and maybe other CNI plugins for Kubernetes.
