The zone setting: unmanage.vm.preserve.nics can be used to preserve Instance
NICs and its MAC addresses after unmanaging them. If set to true, the Instance
NICs (and their MAC addresses) are preserved when unmanaging it. Otherwise,
NICs are removed and MAC addresses can be reassigned.

+Since 4.22, domain XML will be made persistent when Instance is unmanaged from
CloudStack. This will allow to manage the Instance outside of CloudStack using
virsh or other libvirt tools. The domain XML will be stored in directory
/etc/libvirt/qemu.
Review Comment:
```suggestion
Since 4.22, the domain XML of an Instance is made persistent when it is
unmanaged from CloudStack. This allows the Instance to be managed directly
outside of CloudStack using `virsh` or other libvirt tools. The domain XML will
be stored in the directory `/etc/libvirt/qemu` on the relevant KVM host.

+Domain XML is taken from Instance but varies based on their state:

+- Running Instance

where the Instance is running

running before stopping it
Review Comment:
```suggestion
- The domain XML is reconstructed from the Instance details available in
the CloudStack database.
- The reconstructed domain XML is persisted on the last host where the
Instance was running before it was stopped.

in Stopped state.
Review Comment:
```suggestion
.. note::
It is recommended to unmanage Instances while they are in the **Running**
state to ensure the exact domain XML is preserved. When unmanaged in the
Stopped state, some information may be lost due to reconstruction.
