libvirt event before migration

I'm trying to remove a pci device "ivshmem" which can't be migrated before migration.

I have used libvirt hook script which can't connect libvirtd when hooking, so failed to remove pci device .

then, i found libvirt api "libvirt-event" and register with "VIR_DOMAIN_EVENT_ID_LIFECYCLE", but which is the event "before migrate"

here is my code:

libvirt.virEventRegisterDefaultImpl()



def event_lifecycle_cb(conn, dom, event, detail, opaque):

    print ""

    print "=-" * 25

    print "%s event: %s detail %s" % (dom.name(), str(event), str(detail))

    #print "%s: event: %s (%s)" % (dom.name(), VIR_DOMAIN_EVENT_MAPPING.get(event, "?"), event)

    #print "%s: state: %s (%s)" % (dom.name(), VIR_DOMAIN_STATE_MAPPING.get(dom.state()[0], "?"), dom.state()[0])

    if event == 2:

        #

    if event == 3 and detail == 1:

        # delete the pci device 

    print "=-" * 25





def conn_register_event_id_lifecycle(conn):

    conn.domainEventRegisterAny(

        None,

        libvirt.VIR_DOMAIN_EVENT_ID_LIFECYCLE,

        event_lifecycle_cb,

        conn)



# setup connection

#conn=libvirt.open("xen:///")

conn=libvirt.open("qemu:///system")

if conn == None:

    print 'Failed to open connection to the hypervisor'

    sys.exit(1)



# register events

conn_register_event_id_lifecycle(conn)



# event loop

while True:

    libvirt.virEventRunDefaultImpl()

thanks in advance for any pointer
