kvmnet.sys BSOD w/ WinXP...

kvmnet.sys BSOD w/ WinXP...

[Daniel J Blueman]

When using Windows XP 32 installed with TCP/IP and microsoft client
networking, I can reproduce an intermittent BSOD [1] with kvmnet.sys
1.0.0 and 1.2.0, by aborting a large data transfer in an application.

Since this reproduces with 1.0.0 kvmnet.sys, it looks unrelated to the
locking changes that went into 1.2.0, but something relating to when
sockets are closed, flushed or data discarded.

Perhaps the offset into the driver at 0xF761A5A9 - 0xF7618000 may tell
us what is needed to reproduce and hint at what area the fix is needed
in?

Many thanks,
  Daniel

Can you try http://people.qumranet.com/dor/Drivers-0-3107.iso this?
Also please provide the specific way of producing load.
Along with it, please note kernel version, kvm version, qemu cmd line.

Dor

With the updated WinXP 32bit drivers here, I'm finding that the
application is experiences a socket disconnect/loss when upload
starts.

I'm using a software package from lecroy.com
[http://www.lecroy.com/tm/Library/Software/PSG/petracersummit.asp?menuid=8],
which connects to a device over the network and receives data at
~30Mbits/s with two concurrent streams.

Host is Ubuntu 8.0.4.1 LTS w/ 2.6.24-19-generic kernel, x86-64.

Problem confirmed with KVM 74 "1:74+dfsg-0ubuntu2~ppa3h"; qemu version
"0.9.1-1ubuntu1".

Params are:

kvm -hda winxp-next.qcow2 -m 768 -soundhw '' -parallel none -serial
none -net nic,model=virtio -net user

Let me know if you need any more information.

Thanks,
  Daniel
