LinuxCon Japan is the premiere Linux conference in Asia that brings together a unique blend of core developers, administrators, users, community managers and industry experts.
CloudOpen Japan is a conference celebrating and exploring the open source projects, technologies and companies who make up the cloud. It’s built on a belief that open works: for users, for industry and for technology.
On this talk we are going to discuss what has changed on KVM migration since LinuxCon2012.
Migration thread
We discuss the work of moving the execution of outgoing live migration to a separate dedicated thread. Using a separate thread for live migration reduces contention with the IO thread and vcpus: higher throughput and more reliable downtime. Move migration to use synchronous IO.
Block Migration
Now we can migrate storage, independently of how we are handling migration itself.
Migration performance on large guests
What is on the pipeline?
