Virtual Machines ('VM') allow you to runanother operating system(or even the same one) on top of the current system you're currently running. For example, it's possible to run (say)Windows XP on your Windows 7machine in a separate window. This requires that your computer currently uses an x86 (32 or 64 bit)processor (be it Intel or AMD). The virtual machine then virtualizes the hardware so that the guest operating system (theone you're running in a separate window) thinks it the only one running on the machine. The programs running in the guestare isolated from your main computer, making such a system very useful for programmers,webmasters using multiple browsers,and even just the ordinary person who wants to test different software without the latter harming their real machine.And it's also useful if you use a Mac, and want to run Windows programs alongside your Mac software.
Tests performed by Apple in June 2003 using preproduction Power Mac G5 units with application software optimized for the PowerPC G5. Compatible ISP and telephone services required. Your ISP may not support all V.92 features. Modem will function according to V.90 standards if V.92 services are not available. Actual modem speeds lower.
Emulators are slightly different. They allow you to run an operating system that requires (say)an Intel/AMD x86 processor on a completely different CPU (processor). For example, it may allow you to run Windows XP ona PowerPC processor (something that normally won't work, since Windows XP requires an x86 processor). In other words,unlike the VM which only has to virtualize some of the hardware, emulators have to emulate everything, including theCPU. As such, emulators tend to be much slower than VMs.
This page lists both VMs and emulators for the Intel/AMD x86 (32 or 64 bits) processors (meaning that they eitheremulate the x86 or are virtual machines that run on the x86). The guest 'machines' they create may or may not(depending on which software you choose) be able to provide access to your real computer's USB drives, CD/DVD drives,printers, network, etc.
Requirements: Some of the virtual machine software require your computer to have a processor (CPU) withhardware virtualization support.As far as I know, all modern AMD Athlon 64 bit CPUs have this (note: I said Athlon, not the budget Sempron).Things are more confusing where Intel CPUs are concerned, since the support for hardware virtualization (or 'VT' as Intel calls it)seems a bit haphazard across their product range (that is, even if you have a higher-end CPU, it doesn't necessarilymean the chip has VT support). To check if your Intel chip has VT support, look for it inIntel's Virtualization Technology List. Even worse, even if your chiphas such support, some computer manufacturers may have disabled it in the BIOS.
DiskWarrior is arguably one of the best hard drive repair programs for the Mac. It works differently than other data repair programs. Instead of trying to rebuild the damaged data itself, DiskWarrior builds replacement data based off of the original data. It then verifies the new data structure based on the original to make sure it is error free. The utility can help you to create a bootable Mac repair toolbox on your flash drive or external hard disk drive, which can be used in the situation when your Mac does not boot. The software can be used to run diagnostics, repair and recover data, optimize hard disk drive’s performance, defragment the drive, and delete data securely.

Some additional useful terminology that you may find useful: in the world of emulators and virtualmachines, the host refers to your real, physical computer that you're currently using to read thispage. For example, if you're using a computer running Mac OS X, then that computer is your host computer, Mac OS X isyour host operating system, and so on. If you run a virtual machine on that computer, and install (say)Windows 7 into thatvirtual machine, then that Windows 7 is the guest operating system.
Note that this page does not list commercial PC emulators and virtualization software. If you need a commercial solutionfor their support, completeness of implementation, stability, speed, etc, you might want to take a look atVMWare Workstationif you use Windows, orParallels Desktop for Mac and Parallels Workstation,if you use Mac OS X.

This is a special version of the free Microsoft Virtual PC software designed specifically for users ofWindows 7.It requires your computer to havehardware virtualization support inthe CPU. The raison d'être of this virtual machine is to allow you to run Windows XP programs in a virtual modealongside your Windows 7 programs in a highly integrated fashion. Unlike the typical virtual machine,your programs act and behave as though they are directly running within your host system itself, and can interact not only withyour hardware but also your desktop, documents, music and video folders. In other words, this is meant as a backward compatibilitytool for you to run older programs on Windows 7. You should not use this if your intention is to test/debug programs andwant to protect your main system. You can apparently also run Vista and Windows 7 as guest machines.
VirtualBox is a virtualization solution that runs on Windows and Linux 32-bit hosts, and supporting, as guest OSes,Windows NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10, DOS/Windows 3.x, Linux, Solaris,OpenSolaris, OS/2 and OpenBSD. It supports shared folders and virtual USB controllers in addition to the usualfloppy and CDROM drive support. Note that the downloadable binaries can only be used for personal use or evaluation purpose.
QEMU supports the emulation of x86 processors, ARM, SPARC and PowerPC. Host CPUs (processors that can run the QEMUemulator) include x86, PowerPC, Alpha, Sparc32, ARM, S390, Sparc64, ia64, and m68k (some of these are still indevelopment). When emulating a PC (x86), supported guest operating systems include MSDOS, FreeDOS, Windows 3.11,Windows 98SE, Windows 2000, Linux, SkyOS, ReactOS, NetBSD, Minix, etc. When emulating a PowerPC, currently tested guest OSesinclude Debian Linux.
Xen is an open source virtual machine that allows you to run multiple guest operating systems partitioned in their ownvirtual machines. It currently runs on Linux (as the host operating system). Supported guest operating systems includeLinux, Windows XP (work in progress), NetBSD and FreeBSD. Unlike some of the other virtual machines and emulators, however,Xen requires you to have a modified version of the operating system as the guest OS.
Bochs is an open source emulator for IA-32 (Intel x86) machines. It has the ability to emulate a 386, 486, Pentium,Pentium Pro, AMD64, with or without MMX, SSE, SSE2 and 3DNow, with common I/O devices (such as a SoundBlaster sound card,a NE2000 compatible network card, etc) and a custom BIOS.You can run Windows 95/NT, Linux and DOS as guest operating systems in that machine. Your guest OS will be installed in alarge file which the emulator will use to mimic a hard disk for the emulated machine. Supported platforms (and hereI mean platforms on which Bochs will run) include Win32 (Windows 9x/ME/2k/XP), Macintosh, Mac OS X, BeOS, Amiga MorphOS,OS/2, and Unix/X11 systems (including Linux).
JPC is a PC emulator written using the Java programming language,and thus runs on any computer that has theJava runtime environment installed (eg Windows, Linux,Mac OS X, etc). At the time this mini-review was written, the emulator is able to run all versions ofDOS as well as some versionsof Linuxand OpenBSD. Note: if you need to run seriousprograms (other than DOS games), you should probably choose one of the other emulators onthis page. The emulator is probably intended more for academic interestand amusement than serious emulation tasks. (It is after all an emulator running on a virtual machine.)
OpenVZ is a server virtualization software built on Linux. If you have ever signed up with aweb hosting company that provides virtual private servers (VPS),they are probably running some sort of server virtualization software similar to this. The software allows you to create isolated environments torun individual copies of operating systems and provide a supposedly secure virtual environment (VE) that behaves like standalone servers.
DOSEMU is a well-known DOS emulator that runs in Linux (host OS). It can even run Windows 3.x in DOS emulation.
DOSBox is an x86 emulator with a built-in DOS. It was created primarily to run DOS games. It emulates a 286/386 inreal and protected modes, XMS/EMS, a graphics card (VGA/EGA/CGA/VESA/Hercules/Tandy), SoundBlaster/Gravis Ultra sound card,etc. You can apparently even run the old 16-bit Windows 3.1 in the emulator. Host operating systems (ie, platforms onwhich you can run the DOSBox emulator) include Windows, Linux, Mac OS X, BeOS, FreeBSD, MorphOS and Amiga68k.
WINE, which stands for WINE Is Not an Emulator, allows you to run Windows programs in Linux and other Unix-type systems.It is a layer that emulates the Windows API on Unix systems running X.

(There's no video for QEMU for Windows - PPC emulator, runs Mac OS 9.1, 9.2 + OSX 10.0 to 10.5 yet. Please contribute to MR and add a video now!)
What is QEMU for Windows - PPC emulator, runs Mac OS 9.1, 9.2 + OSX 10.0 to 10.5? QEMU is a very versatile and extremely broadly supported open source virtual machine emulator. In 2016, QEMU could finally achieve what has never been possible before: emulating Mac OS 9.0.4, 9.1 and 9.2.2 (albeit still it's quite slow and the sound support is kind of buggy at the moment). Note that QEMU can also emulate Mac OS X 10.0 up to 10.5. At some point in the near future hopefully, QEMU will fully replace SheepShaver, but at the moment, SheepShaver still runs faster in most situations. Advantages of using QEMU vs SheepShaver:
These bundles were put together by 'that-ben' and are intended to be the easiest possible for beginners. Just launch the 'QEMU - Mac OS 9.2.2.bat' (or 'QEMU - Mac OS X Tiger 10.4.11.bat') file and wait 30 seconds for Mac OS to boot up. Nevermind the yellow screen with a VRAM partition not found error, it will go past this without any problem. The Mac OS 9 package contains a 1GB disk image on which Mac OS 9.2.2 is already fully installed. The Mac OS X package contains Mac OS X 10.4.11. BTW, if you need a larger disk image, you can grab one instantly from here: Blank hard drive disk images (3GB HFS up to 30GB HFS+) Networking is fully functional thanks to the sungem driver that's already pre-configured in these downloads. Right out of the box, it will network through your host machine but on its own subnet branch. The virtual machine's IP will be like 10.0.x.x. Your Windows host IP would likely be something like 192.168.x.x but what's nice is that the virtual machine can still tunnel back to your host machine's subnet branch. So, for instance, you could perfectly well make a server/client environment between Mac OS 9 in QEMU and your Windows host machine. Pre-installed software in the Mac OS 9.2.2 package includes:
Pre-installed software in the Mac OS X 10.4.11 package includes:
