checkpoint/restore support not available

Hi

Thank you so much for providing this auto-configuration to play with this great new feature.

I am on an intel based mac, using virtual box and I am hitting the following issue:

When I tried to checkpoint, I got the following error
checkpointing of default/webserver/webserver failed (rpc error: code = Unknown desc = checkpoint/restore support not available)

curl -sk -X POST  "https://localhost:10250/checkpoint/default/webserver/webserver"   --key /etc/kubernetes/pki/apiserver-kubelet-client.key   --cacert /etc/kubernetes/pki/ca.crt   --cert /etc/kubernetes/pki/apiserver-kubelet-client.crt

checkpointing of default/webserver/webserver failed (rpc error: code = Unknown desc = checkpoint/restore support not available)

I checked that the feature gate is enabled in the /etc/kubernetes/manifest directory tree

root@kubemaster:/etc/kubernetes/manifests# grep -i feature *.yaml
kube-apiserver.yaml:    - --feature-gates=ContainerCheckpoint=true
kube-controller-manager.yaml:    - --feature-gates=ContainerCheckpoint=true
kube-scheduler.yaml:    - --feature-gates=ContainerCheckpoint=true

Thanks
