So when does the event channel between the backend & front end drivers break during suspend operation in XEND ?? Also when is the NETIF_INTERFACE_STATUS_DISCONNECTED status sent to the front-end driver? I see code in the front-end driver that processes this status type which results in the front-driver going to a suspend state (like unregistering IRQs etc) Nauzad On Thu, 20 Jan 2005 22:54:25 +0000, Mark Williamson <maw48@xxxxxxxxxxxx> wrote: > > During Save & Migration, XFRD sends "xfr.suspend" message to XEND. > > This results in XEND suspending the domainU.
