CNI and istio issues during running single-node on a non-cloudlab platform.

Version & Branch

VHIVE_BRANCH='hy'
LOADER_BRANCH='main'
CLUSTER_MODE='container' # choose from {container, firecracker, firecracker_snapshots}
PODS_PER_NODE=40
GITHUB_TOKEN=$HOME/.git_token_loader
DEPLOY_PROMETHEUS=false

Expected Behaviour

No warning information after executing kubectl describe nodes No error information after executing istioctl install -y -f $ROOT/configs/istio/istio-minimal-operator.yaml

Actual Behaviour

The logging information of kubectl describe nodes contains

container runtime network not ready: networkready=false reason:networkpluginnotready message:network plugin returns error: cni plugin not initialized

I fix this issue via kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml.

After executing istioctl install -y -f $ROOT/configs/istio/istio-minimal-operator.yaml, it reports

✔ Istio core installed
