Description of problem: When I created a connection with sriov.total-vfs 2 and upped it I saw two new VFs (virtual functions) created. After modifying to 0 and reconnecting I could still saw two. When I modified to 1 it was working well and just one VS was available Version-Release number of selected component (if applicable): NetworkManager-1.14.0-5.el8.x86_64 How reproducible: always Steps to Reproduce: 1. nmcli con add type ethernet ifname \* sriov.total-vfs 2 con-name vfs 2. nmcli con up vfs 3. nmcli con mod vfs sriov.total-vfs 0 4. nmcli con up vfs Actual results: still 2 VFs Expected results: just real device should be present, no VFs Additional info:

deleting when we probe for drivers works as expected but: @sriov_con_set_VF_to_0 Scenario: nmcli - sriov - add 1 VF * Add a new connection of type "ethernet" and options "ifname em2 con-name sriov sriov.total-vfs 1 sriov.autoprobe-drivers false" * Execute "nmcli connection modify sriov sriov.total-vfs 0" * Bring "up" connection "sriov" Then "1" is not visible with command "cat /sys/class/net/em2/device/sriov_numvfs" And "vf 0" is not visible with command "ip link show dev em2 |grep 'vf 0'" is stalled in * Bring "up" connection "sriov" I will file a separate bug for this.
as said, bug 1659514 is still here, in driver mode true it's working well.
