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>
