I believe the following is the correct patch for this - when a guest
is started from a snapshot or from a saved image, qemuProcessStart is
called with VIR_NETDEV_VPORT_PROFILE_OP_RESTORE. From my reading of
the code, the callback will have been removed when the guest was
previously saved, so it will need to be re-added when it's restored.
Yes. I tested for this. In any case of a disassociation the callback
is properly removed.
Dirk - please test this and let me know if it behaves properly.
I just posted an update to my initial patch - sorry for the delay, but
I wanted to make
sure this does not create any other regressions.
My patch is basically identical to yours.
---------------------------------
Currently upon a migration a callback is created when a 802.1qbg link
is set to PREASSOCIATE, this should not happen because this is a no-op
on most switches, and does not lead to an ASSOCIATE state. This patch
only creates callbacks when CREATE or RESTORE is requested. Migration
and libvirtd restart scenarios are already handled elsewhere.
