I'd expect to see the hard disk being seen by the guest, ie.  a
message similar to this in the kernel output:

[    0.610168] virtio-pci 0000:00:02.0: PCI->APIC IRQ transform: INT A -> IRQ 34
[    0.614532] scsi2 : Virtio SCSI HBA

If you're not seeing something like that, then something very
low-level is going wrong about how the disk is presented to the guest.

This is possibly a libvirt or Xen issue.
