What happened?

I am running containerd 2.0.0 with vmm-sandboxer and on top of it I am running k8s with cilium as CNI plugin.

when I start a simple redis pod with vmm runtime class , I see the following error
(combined from similar events): Failed to create pod sandbox: rpc error: code = Internal desc = failed to start sandbox "6b3ffcae3f0bda1df6c78856631d2b7732f3f4118d4706ddb6d34cc8c35c5348": failed to setup sandbox: rpc status: Status { code: UNKNOWN, message: "Others("Other: Failed to add address 2001:db8:7653:299:cafe::ac01: Received a netlink error message Not supported (os error 95)")", details: [], special_fields: SpecialFields { unknown_fields: UnknownFields { fields: None }, cached_size: CachedSize { size: 0 } } }

Host kernel is v6.2

What did you expect to happen?

start pod inside cloud hypervisor and have the pod up & running

How can we reproduce it (as minimally and precisely as possible)?

Cloud Hypervisor 41.0.0
Linux 6.2.0-060200-generic
start a single node k8s cluster with Kubeadm and install cilium cni

Anything else we need to know?

I am running static release binaries.
