[ovs-dev] Virtio Crypto with OVS-DPDK

[Harish Kumar Ambati]

Thanks  IIya for the reply . Please find my comment below.



>>Hi Harish,

>>Why do you want to integrate virtio-crypto into OVS?

>>OVS is an OpenFlow Network Switch, but crypto devices are not network devices.

>>They will not fit in OVS purposes nor OVS architecture.



Let's take a use-case of ipsec running in a guest. A guest with a virtio_net driver, shares a number of virtqueues with QEMU.

Virtio-net backend is supported by OVS. Now, if we want to use crypto device with virtio-crypto? How should we do it without OVS?

I felt OVS is a right place to also provide support for virtio-crypto - especially when it is being used in conjunction with virtio-net.

Please suggest.



Regards,

Harish
