Might want to hold up on the x64 version - I got immediate fail on boot:
Code:
blkfront: xvda: barriers enabled
xvda: unknown partition table
blkfront: xvdb: barriers enabled
Kernel panic - not syncing: No available IRQ to bind to: increase nr_irqs!

EDIT:
Always the same message, but the failure point seems a little random:
