Hi guys
I have a Dell R740 server, on this server I have two Broadcom NetXtreme E-Series Advanced Dual-port 10GBASE-T Ethernet Network Daughter Card NICs, these NICs support SRV-IOV.
The SRV-IOV feature has been enabled in the server BIOS, the feature for network cards has also been enabled in the BIOS.
I installed Windows Server 2019 on the Server, with the Hyper-V role When I'm going to create a new virtual switch I checked the option for SRV-IOV, and when starting the VM everything is ok.
The problem happens when I enable the SRV-IOV feature in the hardware acceleration options of the network card, at this point the network card stops responding, when I disable the feature the card returns to responding. I contacted Dell who replaced the card, but the problem still occurs.
Does anyone know what this problem might be?
