[open question] io_uring nvme passthrough support and how local disk is used in cloud native senario here #272

Closed gaowayne closed 1 year ago

gaowayne commented 1 year ago

hello guys, I have two questions for Dragon ball project.

  1. I see firecracker already support IO_URING and nvme passthrough, do we have plan to integrate these in?
  2. could you please share me how local storage is leveraged in dragonball for the cloud native scenario. it serves serverless deployment. if any case the local disk via virtio is needed?

if there is any guide for dragonball for storage, that will be great for me to catch up. :)

We have already have IO_URING support in Dragonball and we will introduce nvme passthrough ( i.e. PCI / VFIO support) around April.

Let me find if there is any document for you.

Out of interest, are you considering using Dragonball? What kind of support we could offer?

thank you so much. we do have interest to study Dragonball, we have internal drive new features that may be provide better storage Qos for dragonball. I may need fully understand how io_uring with nvme passthrough is used in dragonball, it is virtio backend? guest VM will access local disk via virtio just like standard ECS local disk? my dingding is 太仆
maybe we can chat more on dingding?
