Hi,
we would like to introduce 3 new elements source,access and allocation in memoryBacking element.
For now it was made for numa topology.
<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=*lib dir path* -numa node,memdev=mem Will be added to the qemu commandline
If access is shared then the "share=on" parameter will 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
The access mode can be overriden by specifying token memAccess in numa cell.
The mem-path can be defined by new config parameter memory_backing_dir.
PS: the sometime failing test qemuhotplug was failing also before this patch :)
Jaroslav Safka (4):
qemu,conf: Rename virNumaMemAccess to virDomainMemoryAccess
qemu_conf: Add param memory_backing_dir
conf: Add new xml elements for file memorybacking support
qemu: Add args generation for file memory backing
