Hello @Bernd ,
Right now we are not supporting hyperv, but tomorrow I finish the first PR (Windows hyperv by thiagoftsm · Pull Request #1164 · netdata/go.d.plugin · GitHub) that is bringing general metrics for hyperv. When this PR is merged I will make another that will add metrics for VMs running inside hyperv. So next days we will start supporting the feature that you wants.
Best regards!
