More info. If I disable ACPI with -no-acpi the VM boots but
 then chews up far more of the host CPU than previously. The
only real explanation I can find for this on the guest side
is a very high number of timer interrupts:

    guest > cat /proc/interrupts 
      0:    2575369    XT-PIC-XT        timer
