Release 0.9.1 of GPL PV Drivers for Windows

Release 0.9.1 of GPL PV Drivers for Windows

[James Harper]

I have just uploaded a new binary release of the PV drivers for Windows.
I have tested that XenNet and XenSCSI can unload successfully (eg
upgrade without reboot), but only once this version or newer is
installed.

For now, it's probably best just to replace the .sys files in
c:\windows\system32\drivers with these new ones. I haven't tested how
install.bat works for an upgrade - one thing I haven't implemented is
the drivers behaving properly when a page file is on there - eg xenvbd
should refuse to unload in that case and it probably won't do the right
thing.

I have put the 'stub' drivers back so you can now silence xenvfb and
xenconsole asking for drivers by installing xenstub.

Have a look at the wiki page for more details:

Does anyone have performance numbers for Windows running on these drivers?

An objective and meaningful (hardware independent, more or less) 
comparison would be Linux PV guest vs Windows with PV drivers; both 
network and hard disk throughput.

Hi,

If you look at my posts in the last months, I've conducted a test for
network and disk drivers on a Linux HVM running with unmodified_drivers (PV
Drivers for Linux).

The result was that Linux HVM with PV drivers performed nearly at the same
speed as the Dom0. thus we can say that Windows PV drivers have still some
gap to close, but let's try to do a new test with James' latest drivers.
