Since switching to Proxmox I’ve noticed an issue with intermittent network connectivity on my VMs. I’ve narrowed it down to the realtek based PCI NIC (Rosewill RNG-407-Dualv2) I currently have installed. Basically when I see a ton of these in my syslog:
Dec 14 13:55:37 server kernel: r8169 0000:09:00.0 enp9s0: rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100).
It means it’s time to reboot. I did some digging on it and it appears to be a kernel driver issue. Unless someone in this community has encountered this and knows of a good fix (other than rebooting) I’d rather just ditch Realtek and replace the NIC.
Can anyone recommend a 2 port PCIe (x1) card that has good driver support under Linux and (hopefully) won’t cost me a small fortune? Bonus points if it’s 2.5GbE capable.
No one ever got fired for using intel nics, it’s worth it for the time it’ll save.
ebay has cheap intel gigabit nics which i havent had issues with
I think anything with an intel chip is golden. I have single port intel gigabit nics in all my boxes and zero issues
Intel or Mellanox are both pretty solid.
For older Gbit intel NICs have a look here: https://forums.serverbuilds.net/t/demystifying-intel-pro-1000-quad-port-nics/2401
Especially the virtual nic support used by VMs is only optimized on some of their chipsets.
I hear the latest two 2.5gbit capable generations from Intel have some stability issue though, but I didn’t have the chance to dig into it. Probably still better than Realtek NICs though.
That’s a useful post. Thanks.
We use mostly Qlogic/Broadcom adapters at work, but i think it depend mostly on what hardware you use. Check compatibility lists
Yeah i didn’t read thoroughfully your post and my suggestion might not be the best recomendation for your case…
