[Libguestfs] external call to v2v (vdsm integration)

[Shahar Havivi]

Hi,

I have several question regarding error handling when we call v2v from vdsm:

1. do you have return code values table?
2. how can vdsm determine if operations success/fail assuming vdsm crushed or
   the service restarted.
3. what is the best strategy to cancel blocked I/O calls?

Thanks,
  Shahar.
