Re: [Xen-devel] Is anyone working on HVM Paravirt drivers for windows?
Hi,
We can use HVM Paravirt driver for windows now.
It is included in XenEnterprise3.1.0b1.
Is there a plan to make this driver to open source?

Why? Because of the Microsoft DDK license. There's no requirement
that a Windows device driver developer use the
Microsoft DDK, but in my experience most do. The typical
methodology for a Windows driver developer is to take
the sample code from the DDK as a starting point, and build the
driver from there. But the DDK has some interesting
licensing restrictions that, to me, don't look compatible with
open source. The Microsoft DDK license is available at
http://www.microsoft.com/whdc/devtools/ddk/ServerSP1DDKEULA.mspx
Sections 3 & 4 look particularly problematic.
Maybe somebody out there is developing (or has developed) Windows
drivers without any encumbrances from the Windows DDK.
I think that's the only way we'll see open source Windows drivers.
Thanks for pointing this out.
How about XenSource/RedHat/Novell guys.. any comments?

Hi,
Our current PV on HVM drivers are based upon work that was
submitted to xen-devel back in April. As you might recall, our
focus has been concurrent support of 32 and 64 bit fully
virtualized domains, and all of our work supports this. I'm sure
that the concepts of what we've done, and what was placed into the
open source project starting in July, are quite similar. However,
given the time frames involved, and the base work not being
included back in April, I also have no doubts that the interfaces
aren't identical.
As noted, we have these drivers running and performing extremely
well at our beta customers. We support concurrent usage for both
32 and
64 bit user domains. The Linux code was released a short while
back, and is open source and available for download on our website.
The Windows drivers were completely developed in-house, and there
are currently internal discussions about whether or not we will
release them as open source.

Are they compatible with the current xen-unstable or 3.0.3 releases,

OK.
How about people from XenSource, VirtualIron, Intel, IBM,
Fujitsu..
are you writing windows PV drivers?
