Public bug reported:
Environment:
Stein nova-conductor having set upgrade_levels to rocky
Rocky nova-compute
Boot an instance with a flavour that has a pci_device
Error:
Failed to publish message to topic 'nova': maximum recursion depth
exceeded: RuntimeError: maximum recursion depth exceeded
Tracked this down it it continually trying to backport the InstancePCIRequests:
It gets as arguments:
objinst={u'nova_object.version': u'1.1', u'nova_object.name':
u'InstancePCIRequests', u'nova_object.data': {u'instance_uuid':
u'08212b12-8fa8-42d9-8d3e-52ed60a64135', u'requests': [{u'nova_object.version':
u'1.3', u'nova_object.name': u'InstancePCIRequest', u'nova_object.data':
{u'count': 1, u'is_new': False, u'numa_policy': None, u'request_id': None,
u'requester_id': None, u'alias_name': u'V100-32G', u'spec': [{u'vendor_id':
u'10de', u'product_id': u'1db6'}]}, u'nova_object.namespace': u'nova'}]},
u'nova_object.namespace': u'nova'},
object_versions={u'InstancePCIRequests': '1.1', 'InstancePCIRequest':
'1.2'}
It fails because it doesn't backport the individual InstancePCIRequest inside
the InstancePCIRequests object and so keeps trying.
Error it shows is: IncompatibleObjectVersion: Version 1.3 of
InstancePCIRequest is not supported, supported version is 1.2
I have fixed this in our setup by altering obj_make_compatible to
downgrade the individual requests to version 1.2 which seems to work and
all is good
