Dom0 is a privileged domain that starts first and manages the DomU unprivileged domains. The Xen hypervisor is not usable without Dom0. This is essentially the "host" operating system (or a "service console", if you prefer).
https://wiki.xenproject.org/wiki/Device_Model_Stub_Domains
In older toolstacks (xm/xend as well as xl in Xen 4.1) you can enable a device model stub domain for a guest by specifying the magic string stubdom-dm as your device model: device_model = "stubdom-dm" If you wish you may freely mix the use of stub domain device model and dom0 process device model on a per domain basis within a single system.

If compiling Linux from source for either dom0 or a guest you can now enable Xen support for both through one simple kernel configuration helper, this was added as of v4.2: make xenconfig This lets you build a kernel which can support xen dom0 or xen guests on i386, x86-64 and arm64.

Xen is type-1 hypervisor: it runs directly on the hardware, everything else in the system is running as a virtual machine on top of Xen, including Dom0, the first virtual machine. Dom0 is created by Xen, is privileged and drives the devices on the platform.

Domain0 is the first domain started by the Xen hypervisor at boot, and will be running a Linux OS. This domain is privileged: it may access the hardware and can run the XenControlTools that manage other domains. These other domains are referred to as DomUs, the …
