KVM Virtualization Notes (14)------KVM Virtual Machine Dynamic Migration

KVM Virtual machine Dynamic migration requires no copying of virtual disk files, but requires the same directory structure virtual machine disk files between the virtual hosts that need to be migrated, compared to the need to copy virtual machine virtual disk files in the static migration of a KVM virtual machine. This part of this article is implemented by NFS, and of course it can be implemented by the GFS2 cluster file system, in this paper, dynamic migration with shared storage

There are two types of KVM dynamic migration, one is based on the dynamic migration of shared storage, one is based on dynamic migration based on data block, need qemu-kvm-0.12.2 above version support, OEL6.3 version is qemu-kvm-0.12.1.2, other distributions may have support

Due to limited resources, there is no actual measurement, please forgive me. will continue to be added in the future.
