I have prepared two Fedora 14 Virtual Machine images and published them to sourceforge.net. One includes the RTEMS Development Environment for 4.10, while the other contains a 4.11 RTEMS Development Environment.

This is a low effort way to get started with RTEMS. The VMs were created and tested using VirtualBox. The VM image includes SPARC and i386 target support as well as Eclipse with the RTEMS plugin. Simulators are included for the SPARC/sis BSP and i386/pc386. Qemu is also installed and configured to support testing networked applications with the pc386 BSP. Anyone interested in RTEMS who wants a pre-setup environment to play in is encouraged to use these. See this page for more details.
