I tried booting the guest with 'lpj=10682525' to work around the 
calibrate_delay issue, but that gave me:

[    0.004100] ENABLING IO-APIC IRQs
[    0.004100] ..TIMER: vector=0x31 apic1=0 pin1=0 apic2=-1 pin2=-1
[    0.004100] ..MP-BIOS bug: 8254 timer not connected to IO-APIC
[    0.004100] ...trying to set up timer (IRQ0) through the 8259A ... failed.

[    0.004100] Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot
with apic=debug and send a report.Then try booting with the 'noapic' option.

Booting with 'apic=debug' gives these additional lines:
