VMWare vSphere vMotion Process Workflow

What does the workflow of a vMotion process look like?


1. Validate destination host is compatible.

2. Create a shadow virtual machine on the destination host.

3. Copy each memory page from the source to the destination via    
    the vMotion network.This process is known as pre-copy.

4. Perform another pass over the virtual machine’s memory, 
   copying any pages that changed during the last pre-copy iteration.

5. Continue this iterative memory copying until no changed pages 
    (outstanding to be copied pages) remain.

6. Stun the virtual machine on the source and resume it on the 
   destination.
