After its publication about 10 months ago, the Jailhouse partitioning
hypervisor for Linux [1] reached an important first milestone: all major
features required to use Jailhouse on Intel x86 CPUs are now available.
We are marking this point with a first release tag, v0.1.
This release particularly means full exploitation of VT-d DMA and
interrupt remapping to isolate assigned PCI devices from the hypervisor
and foreign cells. Moreover, the usability of Jailhouse was greatly
improved by the introduction and continuous extension of a generator for
system configuration files. Finally, a framework for writing basic cell
applications is available now. With a few lines of C code you can set up
timer interrupts, read clocks or configure PCI devices for the use in
simple bare-metal real-time applications.
