OVH + Default Kernel = ugh

So, we got an OVH box and we're running Centos 6.7 for KVM visualization. But with this, we ran in to a problem. As you may know, you just can't run KVM on OVH's kernel so we've installed the default one via "yum install kernel".
That went fine and the box is running. But it breaks networking. Why? Because of the network drivers don't work with the new kernel so the solution I found was to install kmod-ixgbe from the ELRepo project. It kinda worked, the module is there but there's an issue with eth0.
"Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization"
The configs (ifcfg-eth0 and 70-persistent-net.rules) are default as installed so I can't see the issue.
Any help?
Thanks!

On some servers the normal kernel for CentOS doesn't work with the network card
Is this the Intel D based one?
EDIT: I had one of the Hosting Xeon D's running Proxmox, I'll see if I can remember what I did to get it working.
Yes, HOST-32L from OVH's mainline
Surely drivers exist that you can compile for the stock kernel.
OVH kernels used (not sure if they still do) to have loadable module support disabled. Have you confirmed you're even able to load modules? If the module can't be loaded, the device won't show up.
You would be better asking somebody to compile a default kernel for you with the appropriate drivers or if its a new machine install a stock centos instead.
Yes, on that line a stock kernel was not even an option.
Back in Feb., @hellb0y posted a tutorial. I haven't tried it myself so, I can't vouch for how well it works.

I have tried this and especially spent a lot of time getting CentOS 7 working with R1Soft kernel modules recently so if its a new server just install a stock kernel from ISO otherwise it needs some magic
Thank you! That actually worked! I had to get the latest version of the driver as the one he listed didn't work but in the end it works! Thank you!
