Xen IA64 Community:


I am working on updating the existing Xen Roadmap Document currently
available in the Xen.org Wiki at
http://wiki.xensource.com/xenwiki/XenRoadMap. Here is the current text,
which is about 3 years old:

The IA64 ports

The IA64 port is making excellent progress with contributions from HP,
Intel, Fujitsu, Bull and VALinux to name but a few. Base performance is
currently excellent, incurring an typical overhead of around 2% on
native. Multiple Linux domains are supported (including support for
virtual SMP), and clean shutdown has been completed. In addition the
source code has been reorganized to produce a clean abstraction layer at
the source level; with this patch applied, the resulting kernel binary
can be run both under Xen and on bare metal. 

Xen/ia64 is also getting close to feature parity with the x86 ports.
Virtual block device using the standard backend/frontend model has been
integrated, and the same set of control tools and commands are used to
manage the system. 

There is also support for VT-i | the hardware virtualization
e-technology for IPF | which allows the running of completely unmodified
guest operating systems along-side paravirtualized domains. Once again,
the control tool set has been aligned with the VT-x model to maximize
compatibility. In terms of hardware compatibility, it has been
extensively tested to operate on the following configurations: 

* Intel Tiger4 * HP rx2600/rx1600/rx2620 (and likely any HP zx1 based
system) * Bull NovaScale <http://wiki.xensource.com/xenwiki/NovaScale>
4000 and 6000 systems, with 5000 to follow * Fujitsu Primequest series 

In terms of future work, the main areas are: 

# Completing/stabilizing the work to give each guest a virtual physical
address space; # Implementing save/restore and migration; # Providing
support for driver domains; and # Additional stability / performance
testing and improvements. 

I would like to get some next text from this group so I can update the
document appropriately. Please email me directly the items you would
like added to the document about this port including new features and
upcoming plans.
