QEMU: a open source machine emulator and virtualizer

QEMU is a generic and open source machine emulator and virtualizer.

When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance.

When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.

To install QEMU on Ubuntu:
~$sudo apt-get install qemu

MeeGo

MeeGo is an open source, Linux project which brings together the Moblin project, headed up by Intel, and Maemo, by Nokia, into a single open source activity. MeeGo integrates the experience and skills of two significant development ecosystems, versed in communications and computing technologies. The MeeGo project believes these two pillars form the technical foundations for next generation platforms and usages in the mobile and device platforms space.

MeeGo 1.1. is announced. It provides a solid baseline for device vendors and developers to start creating software for various device categories on Intel Atom* and ARMv7 architectures.

uClinux: Embedded Linux/Microcontroller Project

The original uClinux was a derivative of Linux 2.0 kernel intended for microcontrollers without Memory Management Units (MMUs). However, the Linux/Microcontroller Project has grown both in brand recognition and coverage of processor architectures. Today's uClinux as an operating system includes Linux kernel releases for 2.0 2.4 and 2.6 as well as a collection of user applications, libraries and tool chains.

Wind River Linux

Wind River Linux is the leading commercial embedded Linux platform and the first to bring companies in all industries the advantages of open source without the risks.

Based on the Linux 2.6.34+ kernel and gcc 4.4.1/eglibc 2.11/gdb 7 toolchains, Wind River Linux 4 is a major evolutionary release of Wind River's market-leading embedded Linux development platform. It supports the full range of embedded hardware architectures and offers the industry's broadest selection of virtualization and multi-core offload capabilities, from kernel-based KVM to the multi-OS Wind River Hypervisor, enabling customers to innovate using today's most advanced multiprocessors.
