Description of problem:

1. Altho I understand the description, it seems a bit redundant and confusing at first, since virtualization is an addon to an OCP cluster, but we're creating a nested ocp cluster on VMs as a hosted cluster. Can we improve wording here?
2. Do we need a section that let's the user choose between hosted/standalone, if there is only hosted as an option? we don't do that for standalone platforms.
3. The description under Hosted or on the Create cluster page doesn't really explain KubeVirt in a hypershift context, where it's a nested OCP cluster but using the same underlying resources for both planes.
4. Perhaps it may help to link to something that explains Red Hat Virtualization? or should we just assume they are aware? https://docs.openshift.com/container-platform/4.12/virt/about-virt.html 
5. Should also use "data center" instead of "datacenter" to be consistent
