To achieve high reliability and redundant deployment, most enterprise networks and their data centers today span multiple physical sites in different geographic locations and deploy similar services on these sites, perform layer-2 communication between these sites. To achieve dynamic resource allocation and management between sites, virtual machines must be freely migrated between data centers. The virtual machine migration process is transparent to users and cannot change the IP address, theref

Then, after restarting the computer, the hard drive becomes the first hard drive, which can start normally, but this method is obviously cumbersome. the map command in Grub can swap disks at run time without having to modify the BIOS.
