“With this acquisition, we are committed to delivering this solution for our customers and providing the support they need both today and in the future.” “Our customers told us they wanted a best-of-breed virtual machine solution that enables them to run their legacy Windows applications, even as they migrate to more modern operating system technology,” said Bill Veghte, corporate vice president of the Windows Server Group at Microsoft. This makes the technology a ready-made ramp to migrate customers from NT 4 to the new Windows platform. Part of Microsoft’s attraction to Connectix’s technology may be because it adds depth to its forthcoming Windows Server 2003 family by allowing existing NT 4 customers to keep their NT 4 applications running as virtual machines. San Mateo, Calif.-based Connectix, which made its name with its Virtual PC software (a line that includes Virtual PC for Mac, Virtual PC for Windows and Virtual PC for OS/2) 14 years ago, has been working to recast itself as a server virtualization software provider with products like Virtual Server, launched in beta in November 2002. Microsoft confirmed late Wednesday it has acquired some assets from partner Connectix that include its Virtual PC and Virtual Server products as well as many of its employees. However, it has the advantage of a simple interface, and virtual PCs are treated as a folder under Windows 7, where you can create a VM in the top bar of explorer.With an eye to beefing up server consolidation on Intel-based servers, Microsoft confirmed Wednesday that it has acquired some assets from partner Connectix, including its Virtual PC and Virtual Server products and many of its employees. The main differences is lack of GUI floppy addition (if you want a floppy disk, you need to directly edit config). It works on 64 bit versions of Windows unlike it's predecessor, but still doesn't emulate a 64 bit environment. Microsoft Virtual PC for Windows 7 was renamed to Windows Virtual PC. Recent compilers will use them as an optimization and may cause your Kernel to not run on VPC.

Virtual PC will throw an undefined opcode exception if a multibyte-nop (e.g. CON: Windows only can't run it on non-windows operating systems.CON: No APM support and minimal ACPI support.Tested on a machine with a Core 2 Duo (64-bit) and it triple-faulted. CON: Apparently doesn't support 64-bit hardware.It doesn't support VBE 3.0 (the one with protected-mode access), BIOS32 for PCI (although that is easily implemented without the BIOS), or loopback mode for the serial UARTs. CON: It only supports a minimal set of hardware - just enough for decent use.See this post on Virtual PC Guy's MSDN blog. Oddly enough, 32-bit color _is_ supported. It looks like some kind of 1980's computer with a defective CRT. CON: 15- and 24-bit graphics modes aren't supported in the emulated S3 Trio (but they are in the real one), they screw up the display.

Just enter \\.\pipe\yourpipename into the configuration page for COM1 or COM2, and connect your debugger (on the host PC) to the same pipe.

PRO: If you integrate a simple debugger and serial I/O into your OS, you can debug it over a named pipe.

PRO: Supports "dynamically expanding" disk images that start at a miniature size and expand when data is added.

PRO: Fixed size disk images are very easy to work with and can be shared by Virtual PC and Bochs :).

PRO: It provides PCI configuration method 1 support and SMBIOS ( Bochs seemingly does not).

Summary: It is okay, but doesn't have an integrated debugger. A free downloadable version of VPC is available from Microsoft's website. It has a very similar feel to the VMware PC emulator, and provides most of the same functions, and is free. (Tested with Linux and several hobbyist OSes.) It natively provides support for Windows operating systems, but, using the 'Other' option, it is possible to install and run pretty much any Operating System. Microsoft Virtual PC is Microsoft's release of a product line they acquired from Connectix in February 2003.
