Hello,

I want to install OpenVZ, but I have a problem with the network card.

The Datacenter told me that this is a driver problem and I need to compile the OpenVZ kernel, with the right driver.

On the server, I installed CentOS 6.4, if I type in SSH

lspci | grep Ethernet


Here is the result

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)


Can you help me?
thank you

Hi,

do you want to say that centos6 kernel works ok, but not openvz rhel6 kernel?

I think you are doing something wrong or there is something not related to driver itself.
AFAIK openvz doesn't alter stock kernel drivers.

can you please give more details?
what kernel version you installed?
did you followed http://wiki.openvz.org/Quick_installation ?
is there some specific network setup (bonding, bridge)?

with openvz kernel:
does network card is detected?
what does show command:
ifconfig -a ?
what boot logs show?

Hello,

Thank you for your help.

I installed this way:

www.virtualizor.com/wiki/Install

It did not work.

I wrote to support virtualizor, they made several test and they wrote me

Sir, can you contact DC support that when you create openvz kernel entry in grub.conf server does not boot.


I contacted the DC, they told me there was a problem with the network card.

The version of CentOS, they propose, is a modified DC Kernel for the network card works.

ifconfig -a

p.s.
if you want to rebuild kernel there is article in the wiki (it's old but I think it will give idea what to do):

Actually, virtualizor is a control panel that supports OpenVZ, among other things. I'm not familiar with it, but their install probably takes care of OpenVZ installation along the way.

This does seem like a kernel problem after all. If the data center requires a modified kernel in order to run plain CentOS, then OpenVZ kernel will have the same problem as the plain CentOS kernel has.

Simply put: find out what modifications they make to CentOS kernel and do the same to OpenVZ one.

Keep in mind, you'll have to do this at every kernel upgrade.

Good diagnosis, bad solution. You don't need to recompile the kernel to fix a bad network driver.

A) Load whatever kernel you want
b) Download the r8168 drivers from here: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langi d=1&PNid=13&PFid=5&Level=5&Conn=4&DownTy peID=3&GetDown=false
c) compile/install the drivers with autorun.sh
d) cd to /lib/modules/KERNEL_VERSION/kernel/drivers/net
e) add r8169 to /etc/modprobe.d/blackist.conf
f) Reboot

I believe all Linux kernels come with the r8169 driver for both the r8168 and r8169 cards but they don't work well on the r8168. It's very well documented.

There is no need to recompile the kernel to change NIC drivers any more. Not for the Realtek, not for Intel, etc.

I hope this helps.
