Genode OS Framework release 14.02 | 2014-02-28
|
||||
##############################################
|
||||
|
||||
| The two highlights of the new release are VirtualBox running on
|
||||
| top of the NOVA microhypervisor and the added support for NetBSD's file
|
||||
| systems. Furthermore, the release comes with new or largely revised
|
||||
| storage components such as a block cache.
|
||||
|
||||
During the release cycle for version 14.02, the development was focused on the
|
||||
topics storage and virtualization, both considered as fundamental for using
|
||||
Genode as general-purpose OS.
|
||||
|
||||
Concerning storage, we took the chance to redesign the existing block-level
|
||||
components to work asynchronously. This way, block requests can be processed
|
||||
in a pipelined fashion and even out of order, which is beneficial to hide
|
||||
device latencies and to maximize throughput. Additionally, there are entirely
|
||||
new storage components, most prominently a new block cache, FUSE-based
|
||||
file-system services, and support for the file systems of the NetBSD kernel.
|
||||
The latter was made possible by the use of so-called rump kernels, which allow
|
||||
the execution of individual NetBSD kernel subsystems at user level. We use it
|
||||
to execute NetBSD's file systems as Genode components.
|
||||
|
||||
Virtualization has become a popular use case for microkernel technology. Until
|
||||
now, however, none of Genode's existing virtualization options such as L4Linux
|
||||
on top of Fiasco.OC or the Vancouver VMM on top of NOVA could be considered as
|
||||
compelling alternatives to commodity virtualization products. With the added
|
||||
support for running VirtualBox on top of the NOVA microhypervisor, we combine
|
||||
the benefits of microkernel technology and capability-based security in
|
||||
particular with a product-grade virtualization solution. Compared to the
|
||||
traditional host operating systems supported by VirtualBox, using VirtualBox
|
||||
on top of Genode/NOVA reduces the trusted computing base for the security of
|
||||
virtual machines by more than three orders of magnitude. For existing Genode
|
||||
users, VirtualBox opens up the ability to run a wide range of unmodified guest
|
||||
operating systems such as GNU/Linux and MS Windows side by side with regular
|
||||
Genode components.
|
||||
|
||||
As is the case for every release, there are many additional improvements all
|
||||
over the place, for example unified interfaces for graphics, support for POSIX
|
||||
signals in the Noux runtime for Unix programs, and a new pseudo file system
|
||||
for the interactive exploration and tracing of Genode's process tree. These
|
||||
and more topics are covered by the detailed
|
||||
