Latest Patents
One of Ping Yang's latest patents addresses the challenge of recovering a virtual machine after the failure of post-copy live migration. Post-copy is one of the two key techniques for live migration, providing deterministic total migration time and low downtime for write-intensive virtual machines. However, if post-copy migration fails, the migrating virtual machine can be lost due to the split state between the source and destination nodes. Yang's innovative solution, known as PostCopyFT, introduces a new approach to recover a virtual machine after a destination or network failure during post-copy live migration. This method utilizes an efficient reverse incremental checkpointing mechanism. The implementation and evaluation of PostCopyFT were conducted on the KVM/QEMU platform. Experimental results indicate that the total migration time remains unchanged while ensuring low failover time, downtime, and minimal application performance overhead.
