Live Migration plays a very important role in the cloud industry, e.g, it's a key component for high availability, load balance, etc. Currently Qemu/KVM gains some notable features to improve the performance of live migration, for example, it supports auto-converge, compress, xbzrle and post-copy, etc, however, in Tencent Cloud we met some challenges to enable them in our productions and realized that they do not work well as we expected in the real world. In this presentation, we are going to present the issues & shortages we found on current KVM/QEMU, then show our solutions to resolve them which will include lockless multithread mode, better vCPU throttle algorithm, redesigning memory mode for compression and xbzrle and so on.
