What were you trying to do that didn't work?
The `nmstatectl show` got error when i40e NIC creating 60 SRIOV VFs
Dec 29 06:45:09 error time=1735472709.087777 sender=org.freedesktop.DBus -> destination=:1.557 error
_name=org.freedesktop.DBus.Error.ServiceUnknown reply_serial=33
Dec 29 06:45:09 string "The name org.freedesktop.NetworkManager was not provided by any .service
files"
What is the impact of this issue to you?
Customer noticed the issue is gone and nmstate has retry on dbus failure, the original issue cannot be reproduced but the `dbus-monitor` can notice the DBUS service of NM is not responding.
Please provide the package NVR for which the bug is seen:
NetworkManager-1.36.0-18.el8_6.x86_64

# Open a terminal with `dbus-monitor --sytem` # Open another terminal with `nmstatectl show` running in a loop. # The show.sh in attached log can be used for this. # Then run below commands with correct NIC name. NIC="ens1f0" echo 0 > /sys/class/net/$NIC/device/sriov_numvfs sleep 10 echo 60 > /sys/class/net/$NIC/device/sriov_numvfs for vf_id in {00..59};do ip link set $NIC vf $vf_id mac 00:01:02:03:04:$vf_id trust on spoofchk off done
Expected results
nmstatectl show got reasonable slow down (less 5 seconds) without any DBUS failures.
