OpenVz Kernel Network Problem (OVH)

Dany123

Hey,

I have installed OpenVz "2.6.32-042stab116.1" on my Centos 6.6 server hosted at OVH.
When i reboot in this kernel the network is unreachable, not visible in ifconfig.

and when i try to ifup eth0 i get "Device eth0 does not seem to be present, delaying initialization".

So i tried to install ixgbe driver but not worked too.

If you have any suggestion please post them Thanks you

Did you install you're server with the OVH Kernel? Is you're networking down? I have a lot of servers at OVH so I might be able to help you

I think the problem is that you installed OpenVZ, remove that and you should be okay.

Yes i have a HOST-32L server, i installed the CentOS 6.7 template, but i can't install it with the original kernel, i get this error (This server must be installed with OVH custom Linux kernel).
Next i installed OpenVz Kernel, but with this kernel i don't have internet connexion, my eth0 don't show up on ifconfig -a and i need to connect with IPMI.

And when i change kernel to the OVH one at boot i have no problem,
I think its something with the driver...

Thanks for the reply !

Another problem is that when using OVZ it's not eth0. It's venet0.

I need OpenVz kernel, that's why it is installed

Thanks for the reply !

Are you opening up a new summer host ?

Them server boards do not come with the drivers for the Network card prebuilt into the default CentOS kernel hence why OVH won't let you install without.

You will need to install the module before rebooting into the openvz kernel using yum or build from source. The module is ixgbe

Hey, it's the OVH kernel, you will need to boot into rescue mode & run this command "dd if=/dev/zero of=/dev/hdX bs=446 count=1 *replace X with the target drive letter." after that reinstall CentOS & the CentOS kernel should install & you should not run into any problems with you're OpenVZ

NIC driver doesn't work with the OVZ kernel, at least not easily. Been there. Ended up not virtualizing the server. I couldn't get it to work.
