Re: [Xen-users] Release 0.9.9 of GPL PV Drivers for Windows
I've installed these drivers on a Win2k3 32bit Machine running debian with own
compiled xen 3.2.1.
The performance seems to be alot better.
The only strange thing is that reads is slower than writes.
Im using nbench for benchmarking and get these results (1 big file at 999mb):
read: 15mb/s
write: 52 mb/s
With 5 files at 10 mb i get:
read: 16.9mb/s
write: 13.8mb/s
How come the read is slower than writes?

Subject: [Xen-users] Release 0.9.9 of GPL PV Drivers for Windows
I've just uploaded 0.9.9 to http://www.meadowcourt.org/downloads
As a reminder, the wiki page is
http://wiki.xensource.com/xenwiki/XenWindowsGplPv
Nothing much changed from 0.9.9-pre3, except that from now on any
attempt to upgrade any of the 'child' devices of xenpci (eg xennet,
xenvbd, xenscsi, xenstub) will be met with a 'must reboot for this
change to take effect'. This should get around any problems of mixing
version, but will still allow 'xm block-detach' etc to work. I think I
may have fixed a BSoD on shutdown too (0x9f).
To upgrade to 0.9.9, you might be able to get away with booting
_without_ /gplpv and performing the upgrade, otherwise you'll need to
remove all trace of the drivers (see wiki) before installing 0.9.9.
I've been tinkering with signing the drivers (just with a self-signed
cert for now). It seems to work okay I'm just working on putting it into
the build script. One thing I found is that on my test server I had
signed 0.9.8 and so the unsigned 0.9.9 wouldn't automatically install as
windows prefers a signed driver over an unsigned one. Keep that in mind
if you've been signing drivers yourself!
Anyway, this release should be a lot more stable that 0.9.8.
James
