 ### qemu-unpriv
 `qemu-unpriv` is run locally and needs no credentials. It has a restricted set of functionality compared to the `qemu` platform, such as:
 
-- Single node only, no machine to machine networking
-- DHCP provides no data (forces several tests to be disabled)
 - No [Local cluster](platform/local/)
+- Usermode networking instead of namespaced networks
+  * Single node only, no machine to machine networking
