Title:
  please include the kernel module VXLAN

Status in linux-kvm package in Ubuntu:
  Incomplete
Status in linux-kvm source package in Xenial:
  New
Status in linux-kvm source package in Bionic:
  New

Bug description:
  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.

  $ grep -i vxlan /boot/config-4.4.0-1039-kvm
  # CONFIG_VXLAN is not set

  When running a kubernetes cluster with Flannel with this image:

  $ kubectl logs kube-flannel-ds-amd64-jfkc8 -n kube-system --kubeconfig=case1-admin.conf
