I was listening to Jeff Woolsey talk at TechEd North America 2012 and he brought up an interesting piece on Windows Server 2012 Hyper-V Live Migration.  There are some interesting enhancements to Live Migration in WS2012 Hyper-V:

  • Idle memory is synchronised between the source and destination host first.  That makes sense.  No point in moving changing memory first because it will change before the first of up-to-10 synchronisation iterations completes.  So the inactive pages are moved first.
  • After that, the active pages can be synchronised.

Live Migration is “70% faster” than it was in the past.
