[PATCH 0/3] Add support for preallocated fd memory

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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)
