A new vnic type ``vdpa`` has been added to allow requesting port that
|
|
utilize a vHost-vDPA offload. The ML2/OVS and ML2/OVN mech drivers now
|
|
have support for the vHost-vDPA vnic type. vHost-vDPA is similar to
|
|
vHost-user or kernel vhost offload but utilizes the newly added vDPA bus
|
|
introduced in the Linux 5.7 kernel. vDPA interface can be implemented in
|
|
software or hardware, when implemented in hardware they provide equivalent
|
|
performance to SR-IOV or hardware offloaded OVS while providing two main
|
|
advantages over both SR-IOV and hardware offloaded OVS. Unlike the
|
|
alternatives, vHost-vDPA enables live migration of instance transparently
|
|
and provides a standard virtio-net interface to the guest avoiding the
|
|
need to install vendor specific drivers in the guest.
