| Thread-topic: | xl miss the logic of memory allocation on NUMA platform |
Hi Stefano In our recently experience, we found xl doesn't have the memory allocation logic on NUMA platform. It will allocate the memory from every node when creating guest: (XEN) Domain 4 (total: 261112): (XEN) Node 0: 64894 (XEN) Node 1: 65406 (XEN) Node 2: 65406 (XEN) Node 3: 65406 For xm, it will allocate the memory on the node where the guest cpu reside: 1348 (XEN) Domain 3 (total: 263160): 1349 (XEN) Node 0: 0 1350 (XEN) Node 1: 0 1351 (XEN) Node 2: 0 1352 (XEN) Node 3: 263160 Is there a plan to add this logic to xl? best regards yang _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
