"HALOS: A Light Operating System" will provide a microkernel-based OS with as principal objectives to (1) run the Jail virtualmachine (2) be POSIX-compliant (3) use Newlib as libc (4) be secure (5) be fast & real-time (6) target x86, PowerPC and Sparc
A virtualmachine inspired by the concept of IBM's z/VM. The goal is to create a secure, fast and reliable server platform with focus on security with the ability to nest more VMs.

Xen is a virtualmachine monitor for x86 that supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation. Linux 2.4, 2.6 and NetBSD 2.0 ports are available. FreeBSD, Plan 9 ports on the way.
The user-mode kernel port is a port of the Linux kernel which runs in a set of processes. The result is a user-mode virtualmachine and a kernel which can be debugged and developed using all of the usual process-level tools.
niab - Network In A Box.
Create a virtual lab network inside one machine. A lab can include routers, firewalls, clients and servers connected by a network specified by you. [Linux Network Simulator, UML, user mode linux]
kissme is a free (GPLed) Java VirtualMachine. It is being developed on GNU/Linux and can run console java applications. kissme is to be used with the GNU Classpath java class library. kissme also provides support for orthogonally persistent java.
UMLWIN32 is a port of linux kernel based on user mode linux (UML) to make linux bootup in a virtualmachine on top of different windows platforms. This provides an authentic open-source alternative to run linux kernel and native linux binaries on windows.
Virtualmachine/emulator; "holding pen" for self-replicating programs written in custom RISC assembly-like language, evolving via random point mutations and periodic fitness-based cullings. Inspired (like Avida) by Thomas Ray's alife simulator, Tierra
OS for embedded and mobile devices based on tiny byte-code interpreter and FORTH language compiler (into platform-independent byte-code). In other word its smallest programming language realization works on any type computer with any OS
eXtendBus is a device sharing mechanism for Virtualization Platform, specially designed for Xen hypervisor. eXtendBus attempts to modify Xen’s architectural features and combine it with extended device driver architecture.
