[Libvir] Is it possible to add an interface to intercept the migration process?



Hi All,

I'm thinking about if it possible to add an interface to let user specified action to happen on destination during the migration, this should be useful for migrating things that have different paths on source and destination.

Allowing specified action(callback) to happen at a time point, e.g., after the config file is transfered and before starting the vm, can bring in a lot of flexibilities considering the migration of devices which are shared but have different paths/views. Giving the dest a chance to recognize these devices and update the config, and then start the vm probably is helpful there.

Comment?

Thanks,
Jack
