In this case controller node goes to the offline state and appears in fuel as new slave node

Workaround:
 Shut down the VM.
 Replace mac address to previous
 Start VM

This is intentional behavior. When you remove (reinstall) "virt" node, all VMs running there are also removed.
If you want to redeploy VMs, please use yours workaround.

We should be able to use node reinstallation + partition preservation for reduced footprint.
I'm not sure that it should be realized in 7.0 but in the 8.0 this should be
