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
CPU0
0: 2575369 XT-PIC-XT timer
1: 9 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
4: 536 XT-PIC-XT serial
8: 0 XT-PIC-XT rtc0
9: 0 XT-PIC-XT virtio0
11: 202 XT-PIC-XT virtio1, eth0
12: 111 XT-PIC-XT i8042
14: 4176 XT-PIC-XT ata_piix
15: 3676 XT-PIC-XT ata_piix
NMI: 0 Non-maskable interrupts
LOC: 0 Local timer interrupts
RES: 0 Rescheduling interrupts
CAL: 0 function call interrupts
TLB: 0 TLB shootdowns
TRM: 0 Thermal event interrupts
THR: 0 Threshold APIC interrupts
SPU: 0 Spurious interrupts
ERR: 0
Cheers,
Erik
