[Xen-devel] [PATCH 04/11] [XEN] NUMA memory allocation strategies

[Dulloor <dulloor@xxxxxxxxx>]

The patch implements the CONFINE/STRIPE/SPLIT NUMA allocation strategies :

- CONFINE : Confine the VM memory allocation to a single node. As
opposed to the current method of doing this in python, the patch
implements this in libxc(along with other strategies) and with
assurance that the memory actually comes from the selected node.
- STRIPE : If the VM memory doesn't fit in a single node and if the VM
is not compiled with guest-numa-support, the memory is allocated
striped across a selected max-set of nodes.
- SPLIT : If the VM memory doesn't fit in a single node and if the VM
is compiled with guest-numa-support, the memory is allocated split
(equally for now) from the min-set of nodes. The  VM is then made
aware of this NUMA allocation (virtual NUMA enlightenment).
