Re: [coLinux-devel] Host crash when running coLinux with VirtualBox in VMX mode

[Alexey E. <al...@gm...>]

BTW: Henry asked if VMX is MMX.

Answer: Well, no - MMX is MultiMedia Extensions, while VMX is Virtual
Machine Extensions. Both developed by Intel. MMX in 1996 and VMX in
2005.

VMX is also know as VT-x or Vanderpool Technology.

VMX has very serious implications on the functionality of CPUs and
OSes, protection levels, and everything. Basically it adds an extra
memory protection ring. It allows for hardware-assisted virtualization
of x86 instructions.

To make use of VMX, a driver needs to be written. VirtualBox's
virtualization driver, aka "vboxdrv", can _optionally_ use VMX.
Alone it works fine, but for some strange reason it dislikes
cooperating with coLinux. :(
