The full stack is a loop of what I paste in the description of this issue. I think it's happend when juno compute node tried to check the compatible with conductor node, but it failed.
I think maybe this line led to the problem : https://github.com/openstack/nova/blob/master/nova/objects/service.py#L81
I tried to set the target_version='1.10' to target_version='1.5'(juno compute_node object version), the problem gone.
