Workshop on Virtual Machine Performance and Security
Challenges of Live Migration in KVM on Same ISA Heterogeneous Processors

Live migration of virtual machines (VMs) is essential in cloud environments, serving various purposes, including server maintenance and load balancing. As many data centers adopt Same ISA Heterogeneous (SIH) processors, such as different generations from the same chip vendor and product lines (e.g., Intel x86 Xeon), the implications of these processor heterogeneity on VM migration remain unclear. This presentation will describe the challenges associated with VM migration across SIH processors, explore the internal mechanisms to manage this migration in KVM-based virtualization, and discuss the impact of a bug we uncovered.
