Folks,
Just out of curiosity,
two questions about Xen project,
First,
I happen to know the word "Xen" is used in two ways:
a) ''Xen'' - Xen is a virtual machine monitor for x86
(http://www.cl.cam.ac.uk/Research/SRG/netos/xen/)
b) ''Xen'' - programming language unites C#,
XML and SQL programming languages.
(http://www.microsoft-watch.com/article2/0,4248,1441416,00.asp)
Both are coming from University of Cambridge
as far as I understand,
so I nearly sure both have the same roots.
It would be nice anybody could tell me the
relationships between different ''Xen''s.
Second,
I know ''VMM-Xen'' is working with Microsoft Research
to bring XenWindowsXP,
and also, the ''C#-Xen'' is a product
from Univ-Cambridge and Microsoft Research.
Speaking about ''VMM-Xen'' (and Xenoservers) project,
is there any "position paper" kind-of-thing
regarding the direction for
the open-source and proprietary products release plan?
Questions might be:-
- I don''t mind XenWindows is not gonna
be open source,
but what else can be proprietary if any?
- Is there any plan to develop proprietary softwares
which support VMM-Xen and realtive projects?
I''m sorry it can be political question easily,
but it''s grateful if I would be able to know
the future plan of the product licensing around
this project.
Best regards,
Latte <latte@heron.spreadwings.to>

It certainly doesn''t have any connection with our VMM.> Speaking about ''VMM-Xen'' (and Xenoservers) project, > is there any "position paper" kind-of-thing > regarding the direction for > the open-source and proprietary products release plan? > Questions might be:- > - I don''t mind XenWindows is not gonna > be open source, > but what else can be proprietary if any? > - Is there any plan to develop proprietary softwares > which support VMM-Xen and realtive projects?(Excerpt from xen/COPYING:) Xen is released under the GPL. However this copyright does *not* cover guest operating systems that use Xen services via normal hypercalls - this is merely considered normal use of Xen, and does *not* fall under the heading of "derived work". Further note that the guest-OS interfacing header files, which includes all files within the subdirectory include/hypervisor-ifs, are *not* covered by the GPL but by a much weaker license: include/hypervisor-ifs/COPYING So: it''s fine to port proprietary operating systems to run on Xen. It''s also fine for users to write their own proprietary tools to control domains running on Xen, though we would obviously prefer people to contribute their tools back to the public source tree.
