Currently, the per-domain path for huge pages mmap() for qemu is
created iff domain has memoryBacking and hugepages in it
configured. However, this alone is not enough because there can
be a DIMM module with hugepages configured too.
The reality is there can be multiple reasons, true?
1. Memory backing source file
2. Some page in the configured hugepages list that doesn't match the
system pagesize
3. Some pagesize for a DIMM module that's requesting a different page
size than the system page size
