GPLPV 0.9.12-pre4 uploaded

[James Harper]

I've just uploaded 0.9.12-pre4 to http://www.meadowcourt.org/downloads

Fixes/updates since 0.9.12-pre3:
. rolled back IRQ restriction which would prevent the drivers from
starting if the pci device wanted to use an IRQ < 16
. fixed another bug in crash dump that could possibly cause corruption
under high Dom0 disk load
. performance improvements to xennet - udp performance is much much
better, I can easily achieve 500MBits/second from Dom0<->DomU or
DomU<->External machine over 1GBit/second wire. Tcp performance should
be as good as before but with lower cpu.

To see some of the the network performance improvements, you'll need to
disable 'Check checksum on RX packets'. It only exists as WHQL fails
without it, even though it isn't a real-world scenario. The 'interrupt
moderation' option appears to cause things to go slower at the moment...
it may reduce load but I think it needs some more tuning!

If anyone can offer any suggestions as to why my Windows 2003 R2 server
takes so long to get to the login prompt after boot with GPLPV but is
quicker without it I'd like to hear them - it seems to get it's dhcp
lease quickly enough so something else about the network adapter or
about the gplpv drivers must be causing the delay...

Yup, this fixed my issue.  Things are looking good now.  This is just
my virtual XP workstation for Outlook and a couple of other programs,
but so far I'd say it 'feels' better.  It's obvious the network driver
is configured, as it's all that shows up in the network applet now.  I
see the Xen Block Device Driver in the scsi section of the device
manager, but is there any clear way to verify the PV block device is
active?  Powershell certainly seemed to load 4-6 seconds faster.

In the future, would I just install new versions over the top of the
current version?

In any event, thanks a ton for all your help getting this up and
going.  Hopefully my XP vm won't be as painfully sluggish any more;
the underlying machine is certainly fast enough.

Regards,
David

I am using Suse 10 SP2 and installed the drivers pre4, but the new network
card says "cable not connected". What do I have to do to make the drivers
work in Suse 10 Sp2? Any configuration at the global XEN level?

I think PV block device is active and work fine if you can see Xen Block 
Device Driver in scsi sections of device manager. And you can check disk 
volume section in device manager. If you cannot see 'QEMU disk...', that 
means PV block device works fine.

Thanks

Yes. That's all I do.

Re: GPLPV 0.9.12-pre4 uploaded

[Patrick Scharrenberg]

Hi!

I just tested 0.9.12-pre4 on a fresh 32-bit windows 2008 with Xen
version 3.3 (64-bit).
After setting the IP address the (guest-)system freezes as soon as
Windows tries to "identify" the network.

Using an older version (0.9.11), the identification process comes
through but as soon as some packets traverse the network interface the
system freezes again.

After disabling "checksum offload" in the driver settings the system
runs stable with both mentioned versions of the GPL'ed drivers.

Is there anything I can do helping to debug this bug?

Patrick

hi James,

I have downloaded your gpl winpv driver 0.9.12-pre4 and installed on 
vista x86. There are some issues:
1, Vista notify me to reboot system again after I installed winpv driver 
and reboot system with gplpv start options.
2, DVD device also cannot work fine. DVD device can be enumerated by 
xenvbd driver. Capacity is OK. But when I try to open it, Vista tell me 
that it need 'UDF' file system support. That's the same issue I have 
meet in my pv drivers.

Thanks
Wayne

That might have been fixed since 0.9.12-pre4. I uploaded 0.9.12-pre7 a
few days ago but had to delete it from the download site as it caused
some problems. I hope to have a new version uploaded shortly.

You can view the fix I am thinking of here:
http://xenbits.xensource.com/ext/win-pvdrivers.hg?diff/3a2121285fc9/xenv
bd/xenvbd.c

but maybe that doesn't fix it for you and there is another problem?

I also have done that in my winpv drivers. But DVD device just can work 
fine on XP/Srv2003. In vista, I just can see a readme file for that DVD 
device. But the same DVD device can work fine on QEMU mode.

Thanks
