KubeVirt vDPA Workflow: From Host to Pod to Domain
summary
Implements a KubeVirt vDPA workflow that wires host SR‑IOV and switchdev representor interfaces through SR‑IOV Network Operator, Multus network attachment and an OVS bridge CNI into a VM via a custom network binding plugin and sidecar that injects the libvirt XML for a vDPA passthrough device. Tests use ConnectX NICs and show high performance bypassing the host but reveal device driver rebind issues on Ampere Altra and no reliable live migration yet.
