[Kimchi-devel] [PATCH 2/5] Fix VM stop error messages handling (backend/UI)

[Rodrigo Trujillo]

The UI was not able to catch the error messages sent from backend when a
user tried to stop a VM. This patch fixes the processes and also change
the 'stop' backend function, then exceptions from "get_vm" are send to
frontend.
