Xen Install Windows
This chapter of Xen Virtualization Essentials will cover in detail the steps necessary to install and run Microsoft Windows 7 as a virtualized Xen guest. Since Windows 7 falls into the Xen category of an unmodified operating system (in other words an operating system that has not been altered specifically to run on the Xen hypervisor) paravirtualization is not an option. Xen PV drivers and Qubes Windows Tools. Installing Xen’s PV drivers in the VM will lower its resources usage when using network and/or I/O intensive applications, but may come at the price of system stability (although Xen’s PV drivers on a Win7 VM are usually very stable). There are two ways of installing the drivers. The team further plans to provide logo-signed builds of the drivers in future commercial Xen offerings. The team may also provide logo-signed drivers via Microsoft’s Windows Update mechanism, making them widely available to anyone running Windows under Xen (not just XenServer) without the need to build the drivers themselves. Upgraded to Windows 10, and Xen says XenTools not installed and ethernet is now shows as a RealTek fast-ethernet. Attempted to reinstall XenTools and as before get the XenServer Tools Installer: The installation of Citrix XenServer Tools has failed. Installation Service Not Found. XenTools, even when on the latest Xen update appears to still not to be ready for Windows 10, even after nearly a year from its release date and 2 months from the free Windows 10 cutoff date.
The computer currently triple boots Ubuntu and a couple of Windows versions. Now I want to add Xen into the mix.
Would it work if I simply made a new partition for Xen, or does it need to take over the entire system?

Alternatively, is there a way to bring my existing OS's inside of Xen (and run them together), so to say?
In case I can't boot into the already installed OS's (together) under Xen, I'll settle for a multi-boot system (2 Windows + Ubuntu + Xen/XenServer) without destroying anything. Then I can do what I want after booting into Xen/XenServer. I'm ambivalent between Xen (with Ubuntu as dom0) and XenServer (with CentOS), as long as they do what I want (multi-boot).

It is possible to run Xen alongside other OSes. It would be just another boot option. Xen is usually installed on an ordinary OS to become a control OS called a Dom0. If you choose, a Dom0 can be your Ubuntu. Or it can be a separate installation on another partition, that is, another OS like Ubuntu with Xen on it in your system depending on your choice.
To have Xen run your other OSes within it, perhaps look into imaging those previous installations and installing and running them as virtual machines. Windows may not like it being picky.
Some research is due.
To add, there seems to be XenConvert which which seems to convert existing installations into VMs https://www.citrix.com/go/products/xenserver/xenserver-xenconvert-free.html

As an example, maybe use XenConvert to convert an existing physical installation to VHD then use VirtualBox to convert to VDI then convert (using VirtualBox's tool VBoxManage) to a Xen VM image.
Some instructions here: https://www.serverstack.com/blog/2012/11/20/converting-virtualbox-vm-to-a-xen-hypervisor-virtual-machine/
An advantage here is that VirtualBox could be used to see if the conversion worked correctly.
More space than the size of the physical installations' partitions concerned would likely be needed. If there is a 100 GB to convert, then space of at least 200GB and a bit more would likely be needed to copy and convert.
The process might be somewhat technical though:http://www.ioncannon.net/system-administration/80/how-to-transfer-linux-from-virtualbox-to-xen/
