== KVM: migrating a VM on Qemu-0.8.2 ==
=== Interface: ===
* Connection Establishment 
 migration listen  [local_host:port [remote_host:port]] -- listen on a port
 migration connect [local_host:port [remote_host:port]] -- connect to a port
 migration getfd fd (socket) -- get established connection (not implemented yet)

* Management 
 migration start online/offline
 migration cancel
Once started, offline migration can not be canceled.

* Status 
 migration status

* Migration Parameters (not implemented yet)
 migration set rate min max offline -- set bandwidth control parameters (min, max, offline)
 migration set total_time seconds -- set migration total_time (seconds)
 migration show -- show migration parameters

* Help
 migration help

=== Example/ HOWTO: ===
A is the source host, B is the destination host:
 
1. Start the VM on B with the exact same parameters as the VM on A, in stopped mode (-S)

2. Establish Connection (either A or B can listen/connect): 

 B: migration listen  BIP:port  [AIP:port] (e.g. migration listen 0:4444)
 A: migration connect AIP:port   BIP:port  (e.g. migration connect 0:4445 192.168.1.15:4444)

3. Start the migration (always on the source host): 
 A: migration start offline

4. Check the status (on either host): 
 migration status

=== Problems/Todo: ===
* handle migration completion better (especially when network problems occur). 
* Online Migration. 
* Finish Interface implementation. 
* Migration does not work while CPU real-mode/protected mode are still changing.
