ZeroVM

ZeroVM is a simple virtual machine. ZeroVM can run (and isolate) 64-bit x86 applications in a 32-bit address space. ZeroVM works under Linux x86_64. For more information check out ZeroVM.org

Installation:

Everything has been tested on Ubuntu 10.04 and Ubuntu 12.04. No issues with VMWare Player. VirtualBox doesn't support SSE4.1, which is used by several of the provided samples.
