 # XXX: --force-interface=all down

+# XXX: Sometimes this leaves "orphaned" datapaths, e.g. a datapath whose
+#      only port is the local port.  Should delete those.
+
+# XXX: This can leave crud in vswitchd.conf in this scenario:
+#      - Create bond in XenCenter.
+#      - Create VLAN on bond in XenCenter.
+#      - Attempt to delete bond in XenCenter (this will fail because there
+#        is a VLAN on the bond, although the error may not be reported
+#        until the next step)
+#      - Delete VLAN in XenCenter.
+#      - Delete bond in XenCenter.
+# At this point there will still be some configuration data for the bond
+# or the VLAN in vswitchd.conf.
