A technician is installing a hypervisor on a host system with a single physical NIC that runs a high-bandwidth network application. The host NIC is running at optimum bandwidth and cannot support additional network traffic. The technician will be configuring eight networked VMs that will be interconnected and on their own dedicated virtual subnet separate from the existing physical LAN subnet.
When networking the VMs, what will the technician need to do to guarantee that the host network's performance is not affected without adding complexity or additional cost to the host configuration?
