Hi,
I want to use virsh to create a VM with the qemu parameter '-object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa node,memdev=mem'.
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>
