Currently, one big gap between Arm64 and X86 cloud platform is that X86 can provide much better instance migration experience than Arm64 platform. CPU comparison and CPU model capabilities have provided Arm64 VM with the ability to live migration among different hardware vendors. This function is the essential function of the data center. From the cloud management framework, we also need to consider the realization of supporting VM live migration.
In this seesion, we will talk about what we have done in most widely used virtulization management tool - Libvirt to provide better live migration capabilities on Arm64 platform and also some details in the newest lightweight cloud management project such as Kubevirt.
With live migration support on Arm64, it can finally benefit the cloud ecosystem for large scale datacenter scenarios which may use different Arm64 CPU architectures and vendors.
