+### Machine gets stuck at `Provisioned` state without `providerID` set
+
+The VM can be created in the provider infrastructure with proper IP assigned but running `kubectl get machines -n eksa-system` indicates that the machine is in `Provisioned` state and never gets to `Running`.
+
+Check the CAPI controller manager log with `kubectl logs -f capi-controller-manager-7f754cf76b-g92ht -n capi-system`:
+
+```sh
+E0218 03:41:53.126751 1 machine_controller_noderef.go:152] controllers/Machine "msg"="Failed to parse ProviderID" "error"="providerID is empty" "providerID"={} "node"="test-cluster-6ffd74bd5b-khxzr"
+E0218 03:42:09.155577 1 machine_controller.go:685] controllers/Machine "msg"="Unable to retrieve machine from node" "error"="no matching Machine" "node"="test-cluster-6ffd74bd5b-khxzr"
+```
+
+When inspecting the CAPI `machine` object, you may find out that the `Node.Spec.ProviderID` is not set. 
+This can happen when the workload environment does not have proper network access to the underlying provider infrastructure. For example in vSphere, without the network access to vCenter endpoint, the `vsphere-cloud-controller-manager` in the workload cluster cannot set node's providerID, thus the machine will never get to `Running` state, blocking cluster provisioning from continuing.
+
+To fix it, make sure to validate the network/firewall settings from the workload cluster to the infrastructure provider environment. Read through the `Requirements` page, especially around the networking requirements in each provider before retrying the cluster provisioning:
