Looking at tests/qemuxml2argvdata/qemuxml2argv-hugepages-pages.args, I
see several instances of "-object memory-backend-file...", so look at
the counterpart .xml file for some examples:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='1'/>
<page size='1048576' unit='KiB' nodeset='0,2-3'/>
</hugepages>
</memoryBacking>
