IA System Virtualization Today Physical Memory I/O Devices Logical Processors Virtual Machine Monitor (VMM) Virtual Machines Binary Translation Paravirtualization Page-table Shadowing IO-Device Emulation Interrupt Virtualization DMA Remap IA-based System Virtualization Today Requires Frequent VMM Software Intervention

18. Terms The ability to drag files or folders between the virtual machine and the host Drag and Drop The ability to use a folder on the host as a mapped drive letter in the virtual machine Shared Folders Virtual Machine Configuration (VMC) file is where all the settings for a virtual machine are stored VMC Virtual Hard Disk (VHD) is the file on the physical computer that a virtual machine uses as a hard disk and perform all the reads and writes VHD A CDROM implemented in software that can share the physical computer CDROM or access ISO images Virtual CDROM Software loaded on the guest operating system that provided increased functionality and performance enhancements Virtual Machine Additions A network created in software Virtual network The Operating software that is installed on the virtual machine Guest OS The actual hardware that is being used and where Virtual PC 2004 is installed Physical Computer The operating system that is installed on the physical computer Host OS The virtual hardware environment provided by Virtual PC 2004 Virtual Machine Description Term
