The root cause is a difference in events reported by different RHV instances. ENG mostly tests with: https://rhvm.v2v.bos.redhat.com/ which reports a created VM as USER_ADD_VM=34 and the VM add is properly handled and reflected in the inventory. However, the RHV instance https://rhev-red-01.rdu2.scalelab.redhat.com/ reports as: USER_ADD_VM_STARTED=37 which is not processed and results in the VM creation being missed and subsequent configuration events failing. There can be 3 events when a VM is created successfully in RHV: USER_ADD_VM(34) USER_ADD_VM_STARTED(37) USER_ADD_VM_FINISHED_SUCCESS(53) And there are two flows. (A) With asynchronous tasks: 1. First, USER_ADD_VM_STARTED is generated 2. When the async tasks are completed successfully, USER_ADD_VM_FINISHED_SUCCESS is generated (B) Without asynchronous tasks there is a single event of USER_ADD_VM. This flow depends on creation flow - if the VM is created without disks then there's no asynchronous tasks whereas when the vm is created with disks (i.e., from a template that contains disks or from the blank template and the add request asks to provision disks) there are asynchronous tasks. MTV should monitor both USER_ADD_VM and USER_ADD_VM_FINISHED_SUCCESS as an indication that a VM was added to cover both flows.

OK, I have permissions to access those environments so I took a look: In rhvm.v2v.bos.redhat.com the blank template is "optimized" for Desktop which means the disks are thin-provisioned and if the add-vm request doesn't include disks, there would be no async task and USER_ADD_VM is generated. In rhev-red-01.rdu2.scalelab.redhat.com the blank template is "optimized" for Server which means the disks are cloned and no matter if add-vm request includes disks or not, the USER_ADD_VM_STARTED would be generated and followed by USER_ADD_VM_FINISHED_SUCCESS. But again, if MTV would treat USER_ADD_VM and USER_ADD_VM_FINISHED_SUCCESS the same way, that would cover all cases - also of different disk allocations. @Jeff, Could you please move this bug to MODIFIED? verified on cloud38 with MTV31 new VM name - > new-vm-test-mtv-31 on > L0_Group_0 on a new plan the new VM appears on the select VMs section as expected Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
