Making VFs persistent across reboots
VFs are not persistent across PF disable, reboot, or recovery. When the PF becomes unavailable, all associated VFs are removed.
About this task
To recreate VFs automatically, use system configuration tools. For example, NetworkManager:
nmcli connection modify <pf_interface> sriov.total-vfs 2
nmcli connection modify <pf_interface> sriov.preserve-on-down 1
These settings are stored in the corresponding NetworkManager connection profile.
