Goal

• When implementing RHEL-26249, netdevs associated to each virtio-net-pci VFs need to be kept. However, the current SR-IOV infrastructure creates and deletes VFs at runtime, which makes hard to keep references to netdevs. Realize VFs when the PF realizes, and keep reusing them to make RHEL-26249 easier.

Acceptance Criteria

A list of verification conditions, successful functional tests, or expected outcomes in order to declare this story/task successfully completed.

• Verify VFs are realized when the PF is realized.
• Verify VFs won't be unrealized after setting 0 to sriov_numvfs on the guest.
