The HVM auto-ballooning is causing problems for paravirtualized guests
on HVM enabled ia64 systems. This allows them to boot again. Maybe we
can take advantage of this when we have better ballooning support on
xen/ia64.

Instead, we probably need to look at cset 10040. I suspect we don''t yet have the ballooning support and need to do the allocation up front.
