I haven't installed the cluster, so I am not sure about the details during installation. When using the fqdn using the migrate command, I am getting: Compute host hypervisor-05.sub.domain.com could not be found. (HTTP 400) (Request-ID: req-b5405272-7938-4e98-8ec1-fa84a37b54a6) While using the short name returns: No valid host was found. There are not enough hosts available. (HTTP 400) (Request-ID: req-bee8f8b1-7218-4ae7-aa71-c4e5a3a84ba5) with the following in the nova-scheduler: No hosts matched due to not matching requested destination (hypervisor-05, hypervisor-05.sub.domain.com) MariaDB [nova]> SELECT host, hypervisor_hostname FROM compute_nodes WHERE host LIKE '%hypervisor-05%'; +------------+---------------------------+ | host | hypervisor_hostname | +------------+---------------------------+ | hypervisor-05 | hypervisor-05.sub.domain.com | +------------+---------------------------+ 1 row in set (0.00 sec)
