Public bug reported:

After successfully updating the name of an instance (from a libvirt/KVM host), I proceeded to delete the instance.
The instance was successfully deleted. However, upon using "virsh list --all", it can be seen that the domain has not been undefined.

Steps to Reproduce:
1. Setup instance with a libvirt/KVM host and SVC storage
2. Spawn a VM called "test-vm"
API --> POST https://<ip>:8774/v2.1/da0be0d560f541d7acccb66104ebe094/servers
3. Update the VM with a new name "new-name-vm"
API --> PUT https://<ip>:8774/v2.1/da0be0d560f541d7acccb66104ebe094/servers/5334ead7-4bd7-4f81-8b41-d833ebf52a9b
body: {{'name': 'new-name-vm'}}
4. Delete the VM
API --> DELETE https://<ip>:8774/v2.1/da0be0d560f541d7acccb66104ebe094/servers/5334ead7-4bd7-4f81-8b41-d833ebf52a9b

Expected Results:
The VM to be deleted and the libvirt domain to be destroyed and undefined.
"virsh list --all" should return:

virsh list --all
 Id    Name                           State
----------------------------------------------------

Actual Results:
The VM is deleted but the domain was not undefined and still appears on the KVM using "virsh list --all".
"virsh list --all" returned:

virsh list --all
 Id    Name                                                    State
