Error [IST0101] (VirtualService cross-namespace.istio-system file.yaml) Referenced host not found: "reviews.default.svc.cluster.local"
Error: Analyzers found issues when analyzing all namespaces.
See https://istio.io/docs/reference/config/analysis for more information about causes and resolutions.

From the spec:

Also, notice that this rule is set in the istio-system namespace but uses the fully qualified domain name of the productpage service, productpage.prod.svc.cluster.local. Therefore the rule’s namespace does not have an impact in resolving the name of the productpage service.
