[OT] Virtualization (WAS: UNIX V7)

12 Jun 2009

...
   I'm
curious, what OS:es and software did virtualisation before
 VMware/XEN/Virtualbox and the like ?  
 Answered in detail by others, but I'd also point out some non-OS
 hypervisors that were around long before VMware etc. Sheep Shaver on
 BeOS in 1998, for instance.

 http://www.bebox.nu/os.php?s=os/macos/index

 SoftWindows, SoftPC and VirtualPC on the Mac could all be considered
 VM environments, allowing one OS to run as an app under another, alien
 OS on an alien platform.

 http://en.wikipedia.org/wiki/SoftPC 
But wouldn't this be more of an emulator than a virtualization? I'll buy
SheepShaver on BeOS, since the code runs "native" on the 603s, but these
x86_PC-on-PPC_Mac packages I would place under emulation since the actual
object code never gets to directly touch the cores (only a translation).
