Ok, it is unlikely to have changed in the 'xm' toolkstack so there is
probably something that changed in the pcifront/pciback.

xenstore-ls /local/.. something /something /some more something :-)
Look for the 'state-0'. Over the life of the guest it should change the value
from
'1' to '6' an then sometimes bounce between different states depending on what
is
happening.
XenbusStateUnknown = 0,
XenbusStateInitialising = 1,
XenbusStateInitWait = 2, /* Finished early
initialisation, but waiting
for information from the peer
or hotplug scripts. */
XenbusStateInitialised = 3, /* Initialised and waiting for a
connection from the peer. */
XenbusStateConnected = 4,
XenbusStateClosing = 5, /* The device is being closed
due to an error or an unplug
event. */
XenbusStateClosed = 6,
/*
* Reconfiguring: The device is being reconfigured.
*/
XenbusStateReconfiguring = 7,
XenbusStateReconfigured = 8
