Announcement: NVMe Live Migration Software Working Group

[Chaitanya Kulkarni]

Hi,

I’m pleased to announce that the NVMe Board of Directors has approved
the formation of the NVMe Live Migration Software Working Group
(NVMe LM SW WG), see [1].

What?

The NVMe LM SW WG will focus on building an end-to-end Linux kernel
solution that follows the NVMe-approved specification and helps ensure
the implementation is aligned with the specification before it is
proposed upstream.

Why?

NVMe Live Migration is one of the more complex features we have
developed over the last four years. The NVMe Board has recognized the
need for a centralized effort around this work. Please bring any related
questions, use cases, or implementation topics to the NVMe LM SW WG.

How?

I am one of the co-chairs of the NVMe LM SW WG and will be coordinating
this effort within the TWG and with the upstream Linux kernel community.
Please reach out to me if your organization is interested in participating.

The prerequisites are that your organization must be a member of the
NVMe TWG and must sign an agreement to participate in the
NVMe LM SW WG. Linux Foundation membership is not required to
participate in this working group.

I look forward to working with you.

_This email is approved by the NVMe Board._

Best regards,
Chaitanya Kulkarni
Co-Chair, NVMe Live Migration Software Working Group

[1] Background

We started this work in August 2022, and it has evolved significantly
over time — from the original SDC 2022 research paper (thanks to
Dr. Stephen Bates) to the NVMe-approved specification.

I've also posted two RFCs to keep the ongoing development aligned with the
kernel community and received valuable feedback from kernel patch
reviews. Thanks to Christoph, Jason, Alex, and others; their input has
helped shape the technical specification.
