== 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:
# Start the VM on B with the exact same parameters as the VM on A, in stopped mode (-S)
# 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)

<li value=3> Start the migration (always on the source host):
A: migration start offline

# 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.
