Any news about this fix?
I'm expiriencing the same issue as Martius.
My situation is:
We are using VMLB and servers with Hyper-V R2 SP1 installed. When we do a Live Migration of the VM with VMQ enabled on the teamed adapters, we completely loose network connection to a VM for some seconds (from 5 till 30 - depends on memory size of a VM).
Also we are using VLANs inside our VMs network adapter properties.
NICs that we're using are: dual-port Intel(R) Ethernet Server Adapter I340-T2 (with Intel Pro Set v.18.104.22.168 installed).
Servers are IBM x3650M3 and they are connected to Cisco 2960G switch.
When I disable VMQ in the network adapters properties, everything run (I mean Live Migration) as it should be, without any disruption in network connectivity, except just one ping loss (sometimes).
I've even tried to adjust *VMQVlanFiltering value in the registry on Hyper-V hosts, as descibed here, but with no luck, seems that Intel network adapters doesn't support this parameter.
Great timing for the question. This is because the update was just published this morning!
You can get it at:
Please give it a try and let us know if it fixes your issues!
Best of luck,
Thanks for that.
I have updated drivers and I can migrate VMs with only 1 ping loss (some times non). However I was in this position late on Friday following some windows updates. Can you confirm where I can find the information from Intel on the current release of drivers for specific NICs rather than the driver suite?
I currently have;
Intel ET on 22.214.171.124 (2/4/12)
Intel X520-2 on 126.96.36.199 (30/03/2012)
If you update Intel Ethernet drivers through Windows updates, the rest of the software suite such as PROSet and ANS drivers will not be updated. Validation is perfromed with packages that contain all the updates. So for the Intel Ethernet updates, I recommend sticking with the packages posted on downloadcenter.intel.com.
As to the current driver versions, here is what I copied from the driver INF files in the 17.1 release:
For the ET: DriverVer = 04/02/2012,188.8.131.52
For the X520: DriverVer = 03/30/2012,184.108.40.206
As you can see, these versions match those you posted. So your base drivers are up to date and match what was included in the recent version 17.1 package.
I hope this helps.
You can get a zip file of the CD at:
The CD download is huge because it has Drivers and software for multiple operating systems, User Guides, preboot utility and images, admin tools, diags, etc.
If you only need the Windows drivers, Intel PROSet, and Advanced Network Services for Windows, then you can get what you need in one of the smaller webpacks:

I hope this helps.
