For XenServer: - the management server "proxies" commands to the VR by using a host plugin. The host plugin communicates on a link local port to the VR/other system vms. For KVM - almost similar to XS, but no plugins are used. The java agent resource runs on the host and communicates on the link local port to the VR or other system vms For VMWare: - system vms acquire an ip on the management network of the pod they are running in. Management server makes ssh calls to this ip.
