Hello Mattm Yes I mean sometimes I have same host/node names with different uuid in compute_nodes table in nova database I must delete nodes with uuid those not match with nova-hypervisor list command. At this time I have the following: MariaDB [nova]> select hypervisor_hostname,uuid,deleted from compute_nodes; +---------------------+--------------------------------------+---------+ | hypervisor_hostname | uuid | deleted | +---------------------+--------------------------------------+---------+ | tst2-kvm02 | 802b21c2-11fb-4426-86b9-bf25c8a5ae1d | 0 | | tst2-kvm01 | ce27803b-06cd-44a7-b927-1fa42c813b0f | 0 | +---------------------+--------------------------------------+---------+ 2 rows in set (0,00 sec) But sometimes old uuid are inserted in the table . I deleted again them. I restarted kvm nodes and now the table is ok. I also restarded each controller and the tables is ok. I do not know because 3 days ago I had same compute nodes names with different uuids.

Hi Matt, sorry but I lost your answer and Gianpiero forwarded it to me. I am sure kvm nodes names are note changed. Tables where uuid are duplicated are: dataresource_providers in nova_api db compute_nodes in nova db Regards Ignazio
It would be easier if you simply dumped the result of a select query on the compute_nodes table where the duplicate nodes exist (you said duplicate UUIDs but I think you mean duplicate host/node names with different UUIDs, correct?).
There is a unique constraint on host/hypervisor_hostname (nodename)/deleted:
schema.UniqueConstraint( 'host', 'hypervisor_hostname', 'deleted', name="uniq_compute_nodes0host0hypervisor_hostname0deleted"),
So I'm wondering if the deleted field is not 0 on one of those because if one is marked as deleted, then the compute service will create a new compute_nodes table record on startup (and associated resource provider).
