Did you reboot into Xen before trying virt-manager?

If you did not reboot into Xen, did you try selecting in 
"Hypervisor and Tools installation" the "KVM Tools" checkbox
before running virt-manager?


By design, if you only select "Xen Server" and "Xen Tools",
the libvirt-daemon-qemu, libvirt-daemon-driver-qemu are not installed
because they are not needed when booted into Xen and running virt-manager.
