� The source MSP keeps copying memory pages to the target in<br />
successive phases until modified pages have been reduced to near zero<br />
� The MSP on the source instructs the PHYP to suspend the mobile<br />
partition<br />
� The mobile partition confirms the suspension by suspending threads<br />
� The source MSP copies the latest modified memory pages and state<br />
data<br />
� Execution is resumed on the destination server and the partition reestablishes<br />
the operating environment<br />
� The mobile partition recovers I/O on the destination server and retries all<br />
uncompleted I/O operations that were going on during the suspension<br />
– It also sends gratuitous ARP requests to all VLAN adapters (MAC<br />
address(es) are preserved)<br />
