The state information includes the current memory content and all the information that defines and
identifies the virtual machine. The memory content includes transaction data and the bits of the operatingsystem and applications that are in the memory. The defining and identification information stored in thestate includes all the data that maps to the virtual machine hardware elements, such as BIOS, devices, CPU,MAC addresses for the Ethernet cards, chip set states, registers, and so forth.
When you migrate a virtual machine with vMotion, the new host for the virtual machine must meet
compatibility requirements so that the migration can proceed.
Migration with vMotion occurs in three stages:
1 When the migration with vMotion is requested, vCenter Server verifies that the existing virtual
machine is in a stable state with its current host.
2 The virtual machine state information (memory, registers, and network connections) is copied to thetarget host.
3 The virtual machine resumes its activities on the new host.
If errors occur during migration, the virtual machine reverts to its original state and location.
