vtism: Efficient Tiered Memory Management for Virtual Machines with CXL
Virtual machines (VMs) impose increasing memory demands, exposing the capacity and cost limitations of traditional DRAM only memory architectures. To address this problem, heterogeneous DRAM+CXL tiered memory management systems have emerged as a promising solution. However, in virtualization environments, the semantic gap between guest and host abstraction layers, coupled with dynamic workload behaviors, hinders precise page tracking, classification, and efficient page migration across memory tiers.
