Hello!

I have a question. I have a server that has 4 network interfaces, I would like to bundle them. I have already tried several times to bundle the cards, but without success. My problem was always that when I started a VM that did not get an IP. Is it even possible to bundle all network cards. I would like to have all VMs keep the same IP. At the moment I only use one network interface.

Code:
Web: xxx.xxx.xxx.24
VM1: xxx.xxx.xxx.89
VM2: xxx.xxx.xxx.90

Can someone make me a suitable configuration or help me with it.

Hello!

Thank you for the quick answer.

Unfortunately my switch does not support "LACP". It is a normal switch without management. I had rather thought about a load distribution and reliability. There are 3 different ones that do this. Mode 0, 2, 4 which is the best.

Mode 4 is LACP, so it does not work

I guess in your setup, only 2 (active-backup) will work.
Round Robin is great as long the counterpart (switch) also provides it.
The problem with RR is that you can't guarantee that the package comes in the correct order.
And some application gets problem with out of order packages.
