Hi, We have this scenario: - VM running Centos-7 - VM running Oracle-8 Then, we shutdown and delete Centos-7 VM (verified by API and UI) Then, we rename Oracle-8 VM (via API) to have the name of the old Centos-7 VM and then stop/start Oracle-8 VM. Rename is working and VM is coming up (status is "up" from API and also in the UI). The problem is that Oracle-8 VM is not really up. it is hanging. not replying to PING nor to SSH. Seems like the root cause is this: - Oracle-8 VM name is indeed Centos-7 VM. but its FQDN (seen in UI) is still its Original name. - So when getting both Centos-7 VM name and Oracle-8 VM name status, I get an answer (via API) about both of them: Both reply with "up" I'm using a simple API to rename the VM as followed (vm_name is Oracle-8 VM name, and new_name is Centos-7 VM name): vm_id_obj = self.get_vm_id(vm_name) updated_vm = vm_id_obj.update( vm=types.Vm( name=new_name ) ) Thanks, Lavi
