Greetings!
I have 2 boxes, one at home for tests and one in a remote data center for my websites. Both run the same OS config.
When I setup last year the home box with Centos 7.3(64) I had problem to activate the network cards and used kmod-forcedeth for this. The remote box was setup by the data center, I don't know if they used it too, anyway network was configured.
Yesterday I updated the home box to 7.4. And after reboot (to 7.4, so), same problem, the network card wasn't recognized. I installed the last kmod-forcedeth release to fix the problem.
I have already updated the remote box through Yum. No error message, ok. But I am afraid to reboot as I don't know if the network card will be recognized, as I have no physical access to the box.
Is there a way to know if network will work, or no?
I have uploaded kmod-forcedeth to the remote box. May I install it right now (Server is updated to Centos 7.4 but still running under Centos 7.3)? Won't it break the network?
The data center just told me "you can later use KVM" but I am a bit afraid And will KVM work if the ethernet card is not recognized?!
Thank you!
Update from 7.3 to 7.4
Re: Update from 7.3 to 7.4
Run lspci -nn | grep -i net. Does that say you have an nvidia network card on the remote machine?
The future appears to be RHEL or Debian. I think I'm going Debian.

Re: Update from 7.3 to 7.4
In addition to the above:
where foo is name of interface (e.g. eth0, enp4s0, ...)
will show the driver currently used by that interface.
Code: Select all
ethtool -i foo
will show the driver currently used by that interface.

Re: Update from 7.3 to 7.4
So your remote server does not use kmod-forcedeth, it uses the 'igb' driver instead and this one is part of the kernel package itself which means that you won't suffer the same problem on this machine.
