Xen users - Nov 2008 - GPLPV drivers for windows 0.9.12-pre3

I''ve just uploaded 0.9.12-pre3 to www.meadowcourt.org/downloads

It fixes some save/restore problems for me which means migration might
work.

Also implemented is some rx irq moderation code. It''s off by default
but
can be enabled in the advanced settings of the adapter. I haven''t yet
done any real performance testing, but I imagine it will need some
tweaking to be effective.

All feedback appreciated.

Thanks

James

I had tried the GPL PV drivers a while back on a VM, and they''re still
installed.  Is it necessary to uninstall old drivers before upgrading
to new?  Are there still instructions for manual uninstall available
somewhere?  I tried installing the last release, and my VM
bluescreened on boot, but it''s fine (if slow) booting without /GPLPV.

I''d love to try these on my VM, but it would be nice to have some kind
of README on install issues, the /GPLPV boot flag, etc.   Maybe that
exists, I just don''t know where to find it?

Thanks a ton for all your work on this, these drivers are sorely needed.

Regards,

Could be multiple reasons for that. What version did you have installed
previously?

Sorry, I don''t remember, it''s been about 4-5 months, I think.

Unfortunately, 4-5 months ago is smack in the middle of a lot of changes
I made.

If it''s anywhere since 0.9.10 it should upgrade smoothly. Anything less
than that and ymmv.

Here are some instructions for uninstalling it completely, after which
you may be able to reinstall it again successfully:

0. Make sure you have a backup
1. Remove xen*.sys from c:\windows\system32\drivers
2. Remove any oem.* files from C:\Windows\inf that contain the string
"net"
3. Remove HKLM\SYSTEM\CurrentControlSet\Services\Xen* from the
registry
4. Remove any key value called "UpperFilters" or
"LowerFilters" from
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ containing the text
''Xen''
(eg ''xenhide.sys'')
5. Reboot

Make sure that /GPLPV is not specified in the boot.ini boot entry you
use when re-installing from scratch (okay for upgrading, just not the
first install). The installer should warn you about this.

Please let me know how you go - if it works as described I''ll put the
removal instructions on the wiki.

James
