Updated HyperV driver no longer loads seth0

[Nimdae]

Binary package hint: linux-image-2.6.32-24-server

This is Ubuntu 10.04 running in a Windows Server 2008 R2 Hyper-V virtual machine.

After installing Ubuntu in the virtual machine, I was able to get up and running the HyperV modules. Once the modules were loaded, I was able to configure and bring up the seth0 network interface. From here, I performed an update, which included a kernel update. Upon reboot, the modules continued to load, but would no longer create a seth0 interface. This results in loss of connectivity.

Loading the legacy network interface gives me eth0, but this connection is unstable.

Booting to the previous kernel brings back a functional set of HyperV drivers.

Hi Nimdae,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 639972

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I ran apt-get upgrade on our Ubuntu 10.04 virtual machine this evening and wound up with the same issue, the eth0 and lo interfaces are present but seth0 has disappeared. Running 2.6.32-24 as Nimdae is.

Got an upgrade to kernel 2.6.32-25 same problem, the seth1 has gone, but appears over eth1.

It works fine, but have to change the interface file (/etc/network/interface) and manually change from sethx to ethx, after the networking restart everything was working fine.
