Closed hemanthnakkina-zz closed 5 years ago

hemanthnakkina-zz commented 5 years ago

Installed Virtlet (image with tag latest) on kubernetes as per the instructions @ https://docs.virtlet.cloud/user-guide/real-cluster/ Enabled Multus with Calico and SRIOV as CNI plugins in kubernetes.

Launched Ubuntu VM spec from examples and pod is in running state and can see qemu process running.

Ping to the POD ip failed.

Error message in Multus log:

2019-06-27T01:29:54-04:00 [error] Multus: Err in getting k8s args: ARGS: unknown args ["K8S_ANNOT={\"cni\": \"calico\"}"]

The error seems to be because of option "K8S_ANNOT" which is only recognized by CNI Genie

Adding IgnoreUnknown option resolved the issue.
