Style nit: we usually check for scalar(keys ...)

It's nice being explicit, but replacing the above two with just
$conf->{balloon}, the whole if expression would fit in one line rather
than six. Either way is fine by me, but the vm_start_nolock function is
already pretty long. Also might make sense to move the PCI stuff into a
helper, if you'd like to give it a shot. But not a requirement for this
patch.

Trailing newline is not required for log_warn().
Style nit: wrong indentation, we don't usually align text like this. It
should just be one more indentation for the second line.
All just nits, so:
