[Lguest] lguest stop/restart and guest (live?) migration

[Matias Zabaljauregui]

Hi, 

   I'm already late with this year's lguest agenda, so while I'm trying
to finish with PAE support details (i hope), I'd like to start learning
about the backgrounds of my next project: guest migration.

I suppose that the first and easier step could be the implementation of
"stop and restart guests" functionality. Then extend it to send the
"guest state" through a socket.  And finally, i could try to use kvm's
algorithm for LIVE migration.

It would be really helpful if you could please give me some initial
hints and advices like :  
 
      * design preferences you may have
      * related documentation
      * source files with reference code from xen or kvm
      * any other ideas regarding guest stop/restart and migration


I really appreciate your help

Matias
