LiveMigration
LiveMigration is a virtualization capability that moves a running virtual machine from one physical host to another with minimal disruption to services. It enables maintenance without downtime, dynamic load balancing, and smoother hardware upgrades by keeping the VM operational during the transfer.
How it works: The VM’s memory, CPU state, and device state are transferred from the source to
Requirements and caveats: LiveMigration typically requires shared storage for virtual disks or compatible remote storage, a
Platform variants: Major virtualization platforms implement live migration with platform-specific terminology. KVM with libvirt supports pre-copy
Limitations and considerations: LiveMigration is most effective for workloads with sufficient available memory and compatible CPU
