RE: [Xen-users] GPL PV drivers for Windows 0.9.11-pre12

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

Steffen,
        This is normal.  The drivers are installed, but the PV devices
aren't surfaced to Windows when you don't run the /GPLPV switch.  This is
the same behavior exhibited by Windows as when one installs a driver for a
non-pnp device that doesn't exist (or when one removes a non-pnp device that
has a driver installed).  Booting with /GPLPV surfaces the PV drivers and
hides the others.  Prior to recent versions, I believe the HVM devices
showed up that way when booted with /GPLPV as well (mine does this in
0.9.10), but regardless you should only get corruption if you have both
block devices showing up as functional (a situation might be possible where
one or both are marked because they not working properly but are being used,
but if you check the properties, you should see "this device could not be
started," or "this device is missing," and both of those messages indicate
that the marked device isn't being used). I believe that there have been
situations where both devices were functional in the past, but that has only
happened on rare occasions with specific circumstances (and even then, only
when booting with /GPLPV to the best of my knowledge).
        Dustin

Hi

After having problems with earlier versions of the gplpv drivers (not
receiving any network packets), I just tried the current -pre12 drivers.
Still the same problem:
- the xennet device does not receive any packets.

Therefore I rebooted to stay without gplpv drivers, as the speed  is mostly
fine for me.
However, now I have some strange effects in the device manager (booted
without /gplpv):
- The xen net device is shown but marked.
- There are two Xen block device Driver entries shown but marked.
- Xen stub device drivers (Console & Virtual frame Buffer) shown but marked.
By marked, I mean this yellow exclamation mark.

Is this normal?
I am fearing to loose my data partition because of the duplicate block
device drivers.

Regards,
  Steffen

Betreff: [Xen-users] GPL PV drivers for Windows 0.9.11-pre12

I've just uploaded 0.9.11-pre12 of the GPL PV drivers for Windows.

Since -pre10 (and -pre11) I've fixed a heap of crashes that were plaguing
xennet under load, and also rewritten the interrupt/event distribution logic
to improve performance.

Under windows 2003 I can now get network speeds of 1-2Gbit/second TX and
600Gbit/second RX, which is considerably better than I was getting before.

Please download it and give it a go.
