Where exactly is the issue there? Please point to the exact doc you are 
refeffing to.
There are several versions and flavors of ovirt (3.4 branch plus minor 
version, 3.5 branch , nightlies; AllInOne, Hosted Engine, 'Normal' 
Engine). For future posts, it is quite helpful if you supply this.

Also, be aware of some general oVirt terminology:
- The (oVirt) Engine is the controller and data collector for your guests,
- A 'Host' is generally a physical machine used to run guests on,
- Hosts are grouped together in clusters of similar hardware providing 
migration and other capabilities,
- A Datacenter is a logical entity of clusters (hosts) and storage 
connections, networks, disks, ect. shared between them;
- VDSM is the daemon running on the hosts to make this all happen; 
imagine it as a super process for qemu processes.

The above said, you basically need a psychical or virtual machine for 
the Engine and some additional hosts to run your guests (not true for 
AllInOne; witch should IMHO only used for demo/lab purposes.

Imagine oVirt Node as something similar to EXi hypervisor; it is an imae 
containing all the stuff you need to add a machine as host to ovirt. The 
same can be achived by installing ovirt from the repos on a (preferring 
minimal) CentOS, RHEL, Fedora install.

There is no problem with that and Windows is very well supported as 
guest OS.
For all of those, have a look on the excellent ovirt admin Guide [1]. 
This is still for oVirt 3.4 - but most of the stuff is true for 3.5 as well.

Have fun with oVirt!
