Hi the xml element to be extended with additional children is the memoryBacking
element.
We would like to introduce 3 new elements source,access and allocation
<memoryBacking>
<source type="file|anonymous" path='/path/to/qemu/'/>
<access Mode="shared|private"/>
<allocation mode="immediate|ondemand"/>
</memoryBacking>
If allocation is immediate then -mem-prealloc should be added to the qemu
commanline.
If source is file then
-object memory-backend-file,id=mem,size=1024M,mem-path=/var/lib/libvirt/qemu
-numa node,memdev=mem
Should be added to the qemu commandline
If access is shared then the share=on parameter should be added to the
memory-backend-file e.g.
-object
memory-backend-file,id=mem,size=1024M,mem-path=/var/lib/libvirt/qemu,share=on
