CPK files for win2k8_32

IIUC the problem is that a bridge erased the 3 QoS priority-bits. This can be a physical bridge (probably not the case) or a software (bridge, firewall ...) on the host. 
I asked mst for advice, and he looked into slot-2 10.66.73.35 (QE lab).
There was no need for 
"disable bridge netfilter"
since it was disabled already.
mst did:
"service iptables stop"
"rmmod ebtable_nat"
"rmmod ebtables"

If this is the right host then please try again after these changes. Otherwise, please repeat these changes on the relevant host(s) and try again.

If it doesn't solve the problem then we will probably need to run tcpdump on the host(s) to see where the bits were erased.

Thanks, Ronen.

Hi Ronen,

   QE submit window 2008 32 bits and window 7 32 bits in WORKGROUP.And I will attach the results,please wait.

Thanks
Min

The Latest testing results for windows 2008 32 bits,actually I also submitted a job in the domino.The job passed at last.

Thanks 
Min

Hi Ronen,

I have tried win7-32 in work group environment, I followed mst did
"service iptables stop"
"rmmod ebtable_nat"
"rmmod ebtables"

job still failed,please refer to the attached of "win7-32 NDISTest6.0(priority).cpk" for details.

We will try again on win7-32 in Domain environment and update the result later.

Best Regards,
Dawn

so, run tcpdump -w on host on both on tap devices and bridge
and compare them, see if qos has been modified.

The server lost these settings. We need a persistent setup

Revised instructions (should be persistent after boot too). Please also update your WHQL document:

Add the following 3 lines to /etc/sysctl.conf
 net.bridge.bridge-nf-call-ip6tables = 0
 net.bridge.bridge-nf-call-iptables = 0
 net.bridge.bridge-nf-call-arptables = 0
run "sysctl -p /etc/sysctl.conf"

"service iptables stop"
"chkconfig iptables off"

"rmmod ebtable_nat"
"rmmod ebtables"
Add ebtables_nat and ebtables to /etc/modprobe.d/blacklist.conf

I only see the attachment from Sep 8, but it probably isn't relevant since the firewall was probably active.

Hi Ronen,

According to your revised instructions we will try this again with the new driver (virtio-win-prewhql-0.1.16) with firewall turning off, and update the result later.
We will also update the WHQL document, thanks for your reminding.

Best Regards,
Dawn

Hi Ronen,

I have tried win7-32 in Domain environment for 2 times with the new driver (virtio-win-prewhql-0.1.16) and set the environment according to your revised instruction:

Add the following 3 lines to /etc/sysctl.conf
 net.bridge.bridge-nf-call-ip6tables = 0
 net.bridge.bridge-nf-call-iptables = 0
 net.bridge.bridge-nf-call-arptables = 0
run "sysctl -p /etc/sysctl.conf"

"service iptables stop"
"chkconfig iptables off"

"rmmod ebtable_nat"
"rmmod ebtables"
Add ebtables_nat and ebtables to /etc/modprobe.d/blacklist.conf

From guest, I disabled firewall. Job passed without any error, looks like win2k8-32 and win7-32 can pass in domain environment easily, I'll try these 2 guests with fresh system in work group environment with the instruction you told me and update the result later.

Best Regards,
Dawn

Tried on win7-32 in work group environment, this job passed without any error and all guests also passed in domain environment.
