Xen users - Mar 2007 - Is there windows version (windows host, linux guest)? / Question about license.

Hello, just wanted to ask two questions. I coudln`t find an answer on
the web.

Is there a windows version of xen? I want to download, install and test
xen on windows as host and use a paravirtualized linux then. But I can`t
find a windows binarry to download on the page?

About the license... All websites say xen is open source (GPL)... All is
open source not just a part.

I don`t want to be insolent but... Why there are paid versions of xen?
Is there only the full source available for all versions but not all
binarys? Only the starter edition is free and the enterprise edition
binarys cost money?

So, if it`s fully open source... What could prevent someone to create a
fork and to provide binarys of all versions?

No, right now the "host" (domain 0) needs to be a Xen-aware OS.  So
that''s
Linux or NetBSD (or the Xen port of OpenSolaris).

XenExpress / XenServer / XenEnterprise (which I think are basically all the 
same software with various levels of features enabled) use a different set of 
management tools (which are not open source) and provide additional benefits 
(e.g. pay for support, paravirtualised device drivers for Windows guests to 
improve perfomance).

XenSource and others provide binary versions of Xen.  Some alternative 
management tools exist - Redhat distributes RHEL 5 with their virt-manager 
app, for instance.  And Virtual Iron is also selling and enterprise 
virtualisation product based on the core hypervisor code of Xen, plus a 
different set of tools.

Hope that helps clarify things somewhat.

Cheers,
Mark
