23. Hands-On Virtual Computing

24. 24 Virtual Machine Hardware Configuration (continued) COM and LPT ports –Administrative console can be used to configure a virtual machine to use standard COM and LPT ports USB ports –USB has become the standard interface for many peripheral devices CD/DVD devices on a virtual machine –Virtual machine can be configured to have virtual CD/DVD devices that can be linked to the host computer’s physical CD/DVD-ROM drive

25. Hands-On Virtual Computing

26. 26 Virtual Machine Hardware Configuration (continued) Floppy disk support –Only one virtual machine can be linked to the host computer’s floppy drive at a time –With virtualization software You can link the virtual machine’s floppy drive to a physical floppy drive or redirect it to a floppy image file

27. Hands-On Virtual Computing27 Virtual Machine Hardware Configuration (continued) Disk support features –With virtualization software, a virtual machine can use a specially formatted file (virtual disk) on the host computer as though it were an entire drive –When you create a virtual machine, you specify: Type of virtual disk Amount of disk space (fixed or dynamic) to reserve for it on the host computer

28. Hands-On Virtual Computing28 Saving the Virtual Machine State Important feature in virtualization software –Being able to save a virtual machine’s current settings and disk contents Nonpersistent disks –Changes made to a virtual machine are used only in the current session Snapshots –Allow you to return a virtual machine to a specific point if you have problems

29. Hands-On Virtual Computing

30. 30 Parenting and Cloning Virtual machine parenting –Enables you to have a master (parent) copy of a virtual machine that can be distributed to other users –Is closely related to snapshots and undo disks In VMware –Virtual machine created from the parent is called a clone

31. Hands-On Virtual Computing

32. 32 Network Support With virtualization software –Virtual machine can have one to four simulated network adapters (NICs) Virtual network adapter –Can be configured in a number of ways, including local, bridged, or shared (NAT) When a virtual machine is in local mode (called “host-only mode” in VMware) –Its emulated NIC is plugged into a virtual switch

33. Hands-On Virtual Computing33 Network Support (continued) Bridged mode –Often discouraged in testing environments Shared (NAT) mode –Allows access to outside networks yet isolates the virtual machine, preventing it from sending and receiving packets across the physical network

34. Hands-On Virtual Computing
