Hmm, let me ping Andrew, he might know. Andrew, do you remember what fix
you needed to get Dom0 to boot when you had more than 64GB of memory
with the VT-d enabled?

From the xen-4.0-testing.hg repo:

x86/iommu: account for necessary allocations when calculating Dom0's
initial allocation size

As of c/s 21812:e382656e4dcc, IOMMU related allocations for Dom0
happen only after it got all of its memory allocated, and hence the
reserve (mainly for setting up its swiotlb) may get exhausted without
accounting for the necessary allocations up front.
