Dell stated the following in response to questions I had: Here are our observations:
Is this issue seen on other distros? ---> No, observed only on Ubuntu. Which release and kernel version of Ubuntu is this? ---> Tried on Ubuntu 22.04, 24.04 Did you run these commands as root? ---> Yes, tried with root only, default user didn't allow to make changes for SRIOV. Which upstream kernel did you check? ---> All, Issue is seen on all. We were able to create VFs on RHEL and SLES even though ports are not connected to network, but not in Ubuntu OS. we got workaround for this and want to know the reason for this behavior.
