Connectix’s Virtual PC for Windows: To run Linux?

From The Register: “An x86 emulator for an x86 platform? No, it didn’t seem to make much sense to us
either. Virtual PC began life some years back on the Mac to allow users to run
Windows apps. It’s essentially a virtual machine that fools x86 apps and operating
systems into thinking they’re running on a native CPU.

But if you are running on an x86 processor, what’s the point? According to
Connectix, it’s all because you want to run multiple operating systems
simultaneously without having to reboot from one to another. Virtual PC lets you run
an extra x86 OS, which thinks it’s running on a PC all of its own; Connectix’s code
simply relays all the relevant hardware calls directly or via Windows.”
