No topic for tomorrow, but I'll be online.

Note, the US just did its Daylight Savings thing, so the local time might be
different for you this week.

Note #2, PUCK is canceled for the next two weeks as I'll be offline.

Future Schedule:
March 20th - CANCELED
March 27th - CANCELED

Would there be a slot available on April 3rd?
I'd like to have a discussion about KVM uAPIs for TDX and SNP Live Migration.

CC the ones who would be interested in joining the discussion.
(Hope more folks working on the SNP migration part could join)

Thanks,
Wei

If there is going to be an April 3rd PUCK, we would like to have a discussion on TDX base series
upstreaming strategy.

Thanks,
Rick

There will be a PUCK, I'll add TDX upstreaming to the agenda.

What exactly do you want to discuss and/or achieve? We can have a handwavy
discussion about TDX's needs for live migration, but there's basically zero chance
you'll get concrete feedback on exact uAPIs at this stage (we haven't even nailed
down the core TDX and SNP uAPI). Doubly so without first giving people *something*
to look at. Even a very rough RFC would go a long way toward showing/describing
the problem you need/want to solve.

The first talk aims at a high-level discussion, for example, what kind of uAPIs are
needed (not concrete feedback on each uAPI detail), in terms of what are conceptually
common in live migration of a TD and SNP guest.

I think from the uAPI design perspective, the migration part could be independent
from the core TDX and SNP uAPI. Please see the slides attached.
