No, don't get that confused. As of lately, Fedora 25 has updated to kernel 4.9.11 as well. But this is just coincidence. This is not the Xen4CentOS Dom0 testing-kernel, but the package from Fedora's update repos. That testing kernel is used on the guest along with Xen4CentOS Xen hypervisor packages to make a Xen4CentOS (7) virtualization host as guest on kvm. I just happen to run my workstation with Fedora+KVM. For any virtualization testing, I use nested virt and create Xen virtualization hosts as kvm guests for testing puposes.
