Hi folks-
if it's not too late for the schedule...
I am starting to tackle VM live migration and hypervisor clustering over
switched CXL memory[1][2], intended for cloud virtualization types of loads.
I'd be interested in doing a small BoF session with some slides and get
into a discussion/brainstorming with other people that deal with VM/LM
cloud loads. Among other things to discuss would be page migrations over
switched CXL memory, shared in-memory ABI to allow VM hand-off between
hypervisors, etc...
A few of us discussed some of this under the ZONE_XMEM thread, but I
figured it might be better to start a separate thread.
If there is interested, thank you.
Hi Dragan,
Thanks for bringing up this topic. I'd be very interested to be part
of this BoF, as I'm also interested in using CXL.mem as a live
migration mechanism.
Thanks for cc'ing me, this would be very interesting to talk about. Count
me in!

[2]. Based on CXL spec 3.0
Dragan: I'm curious about the reference to CXL spec 3.0 here, is there
something specific about 3.0 that this work depends on or should we be
good-to-go with 2.0 as well? (Are you referring to 3.0 for security
extensions?)
Sorry hit send too soon, and then had hosting provider issues... the
hypervisor clustering part[1] might not work on CXL 2.0
