Hi,
we would like to introduce 3 new elements source,access and allocation
in memoryBacking element.
<memoryBacking>
<source type="file|anonymous"/>
<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
Also token memAccess in numa cell is used (if not present, default value
from memoryBacking is used)
