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?

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. [1].
