With current design, kubevirt data-center is used to serve all of kubernetes clusters.
The data-center is being added and marked as initialized.

On Kubevirt provider removal, we remove all of that cluster resources (cluster, hosts, vms, templates and networks).
However the data-center remains.

If we wish to remove the 'kubevirt' data-center when the last kubevirt provider is removed, we need to add that to:

Comment 5 Pavol Brilla 2020-04-21 11:09:19 UTC 
Once all kubevirt/cnv providers are removed, DC is removed as well.

	
Data Center kubevirt was removed by SYSTEM
