[LSF/MM/BFP ATTEND][LSF/MM/BFP TOPIC] BoF: NVMe VFIO Live Migration

[Chaitanya Kulkarni]

Hi,

Since I've conducted NVMe VFIO Live Migration talk at SNIA SDC 2022 [1],
there has been significant development in this area in the NVMe TWG and
on the mailing list with RFC kernel implementation posted by Intel [2].

Although RFC implementation is far from the actual implementation since
there is no support for the standards for NVMe Live Migration
commands, it did bring up some interesting points about how the
kernel implementation would look like especially between VFIO and NVMe
subsystem.

I'd like to propose a BoF session for NVMe Live Migration and
discuss what are the kernel side implementation issues we need to 
address apart from the discussion we had on [2].

Please note that we will _not_ be discussing any NVMe TWG standard
specific topics in this BoF, but this session will be focused on
mailing list discussions only.

Required attendees for this session:-

Christoph Hellwig
Jason Gunthorpe
Keith Busch
Martin Petersen
Javier Gonzalez

Sounds like a good opportunity to discuss the Linux side of this
implementation.

By LSF/MM we should be quite far along alot of the migration ecosystem
work in kernel/qemu/libvirt/etc

Thanks,
