[Kimchi-devel] [PATCH] Bug Fix #282: Disable Start/Stop network buttons while wait backend lag

[Rodrigo Trujillo]

When the user tries to Start/Stop (up/down) a network, there is a lag in
the backend, and it was possible to click on start/stop/delete again,
and again, generating errors. This patch disables the buttons and shows
loading gif to user, avoind this kind of error.
