Does anyone use SRIOV to develop virtio-net

Hi,

    Recently, I use an V7-330T to develop a function called virtio-net, though it hard, but it works now.

The driver needn't be changed and the add-in card would work as an virtio-net device.

   Now, I am working on SRIOV, what I want is to use SR-IOV techbology to implement 256 functions.

and every function could be used for an VM.

    Now, when I cfg my FPGA card as a pci host device and pci pasthrough, the VM works normal and the performacne is good.

but i found there are little guy working on it, I want whether someone could discuss with me.

Best Regards

Liuluren

yeah, we are researching virtio-net and sriov. As i know, Intel has implemented virtio-net by FPGA. It can support SRIOV passthrough and vDPA for VM live migration.

Maybe, but I know it is hard to support VM live migration. Some friends have try ,but they failed.

Later, I would working on the VM live migration since there are bugs in SRIOV implement in my codes.

Hi guys,

       Both my virtio-net and SRIOV works, the performance is good. and I wrapper it as an ip core, next step, I would develop TSO and LRO, its code is done now.

TSO supports 64kBytes and LRO support 32 sessions to 64kBytes.
