From what I know, the Xen Hypervisor is not running in a VM, but on "bare metal". There is one privileged VM called Dom0 which is used to control the hypervisor and which provides drivers for the hardware.
I recommend reading https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide (e. g. section "A brief look at Xen Project architecture")

I don't know enough to give an answer to that one...
