Hi Shreyas-
speaking strictly for myself, sounds interesting

Thank you, Dragon.
Btw, we can demonstrate the VM live migration with our FPGA based CXL memory and our demonstration today. We are not application expert, looked at the last diagram in your link and we are confident we can achieve it.
Will there be any interest from the group? I can present for 15 mins and Q&A.
Regards,
Shreyas

Hi Dragon,
The concept is great to time share the CXL attached memory across two NUMA nodes for live migration and create a cluster of VMs to increase the compute capacity.
When and where is the BoF?
It's a proposal sent under (CFP), it has not been accepted yet. The agenda is selected by the program committee based on interest. The current proposal is for LSF/MM/BPF summit[1] running May 8 - May 10th, but it's not happening if not approved by committee.

Subject: [LSF/MM/BPF TOPIC] BoF VM live migration over CXL memory
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.
