Palacios is an open source virtual machine monitor developed as part of the V3VEE Project.

Palacios is intended to facilitate research and teaching in computer systems, computer architecture, and high performance computing. It is released under the BSD license. Community use and contributions to the source base are strongly encouraged!

As of version 1.3, the preferred host OS for Palacios is the Linux Kernel. Palacios can be compiled into a kernel module that can then be inserted into existing Linux kernels. Palacios 1.3 can also be readily incorporated into the Kitten Lightweight Kernel, and other OSes.

    • Getting Help

  • The Palacios Technical Report is the most important documentation for Palacios 1.3 and later.
  • Release 1.3 has been tested with Kitten 1.3.0, Linux 2.6.32 and several later Linux versions as host OSes. In addition to compact Linux host configurations, we have also tested Palacios in unmodified Fedora 15 environments, and in Red Hat
  • There is also an Open Discussion Group for Developers, as well as a General Open Discussion Group On V3VEE.
