Installing Linux KVMs on Hyperflex hardware.

Installing Linux KVMs on Hyperflex hardware.

FI 6332 is connected to the VIC card through QSFP-40G-SR-BD.

On the server port of the FI, it looks like 40G, but on the Linux interface it looks like 10G.

Why is that?

Hello @HyunJun Lee,

Do you verify the interface configuration on your Linux system. Ensure that the interface is correctly configured to negotiate and operate at 40Gbps.

You can set the interface speed and duplex settings manually if it's not negotiating properly.

I checked the Linux configuration and tried to change it manually, but it didn't apply 40G.

For further verification, I changed the OS to VMware and installed it, but this time the Vic link is down and cannot be verified.

Problem solved. Once it appeared to be 10G, the link was down and down because the uplink interface was down in the FI. Regardless of the presence or absence of communication, if the FI's uplink is not activated, it is not pinning, so the phrase ENM source fail is checked in the vif pass.

The VIF is linked up and the OS automatically recognizes the 40G speed.

Thanks for your feedback @HyunJun Lee
