Big Picture: • “It’s like VMWare Player, except you can build an entire network in it.” • Multiple machines • Switches • Routers • Multiple subnets
Hypervisor/Virtual Machine Monitor (VMM) • HOST MACHINE – runs the hypervisor software • Our is carol.cs.usna.edu • GUEST MACHINE – any VM running on the host • The host: • Runs multiple guest VMs (much like VMware Player) • Connects the hosts with virtual switches • May allow the hosts to access physical hardware such as network cards or Wireless AccessPoints • Hosts can either: • be sandboxed in a virtual network (unable to access Internet) • access the outside world like any other server (e.g. webster)
Physical layout for Hypervisors Type-1 (Native) hypervisors Type-2 (hosted) hypervisors e.g. VMware Workstation e.g. VMware ESXi VM VM VM VM VM VM Hypervisor Hypervisor OS Hardware Hardware
Examples of servers running inside a hypervisor: • rona – SI110 linux server • nuzee – faculty linux server
Semester project • We will spend the semester building a complete network in a virtual environment (ESXi on carol) • Add ESXi skills to your resume • Hypervisors are your present and future • 4x student subnets + instructor subnet • 5x servers / subnet • 2x routers / subnet • 2x switches / subnet • Total of 45+ devices replaced by a single rack-mounted server
Other names you will see • vSphere – suite of tools to manage networks on an ESXi server • vCenter – centralized platform for managing multiple vSphere environments • vCOPS – “vCenter Operations Manager”: a VM that runs inside carol to manage its own ESXi server gertie.cs.usna.edu (vCenter server) carol.cs.usna.edu (ESXi server) peggy.cs.usna.edu (ESXi server) (VCOPS) Win 2008 (manages carol & peggy)
Software for accessing virtual network VMware vSphere Client VMware vCenter Converter Access any VM in the hypervisor Copy VMs from local machine to hypervisor
Tour vSphere Client • Home • We will mostly be concenred with “Inventory” section • Inventory → VMs and Templates • Inventory → Datastores and Datastore Clusters • Inventory → Networking
