Hmm, "bus=scsi"?  Although this is Xen, this seems to be a surprising
choice.  I would have thought bus=xen (or possibly bus=virtio) would
work better.

If you look at the guest kernel output, you can see that no sda hard
disk device is detected at all, which would mean that the guest
doesn't have the right device drivers to see this sort of disk.  And
since there is no model=... in the libvirt XML I'm not even sure what
device driver would be required here.  Xen probably chooses a default
SCSI device to emulate.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
