Explanation/Reference:
Explanation:
live migration – is similar to warm migration, except that the guest is not suspended during transmission. Instead, the LDoms manager keeps track of memory changed while state is being transmitted, and then makes followup passes to retransmit data changed state information. A brief pause is used at the end to transmit residual changed state. This method is typical for virtual machine systems that provide live guest migration.
