The major change from v17 is the patchset is now based on memory backend. Example command line:
./x86_64-softmmu/qemu-system-x86_64 -hda /path/to/image.img -smp 2 \ -object memory-ram,size=512M,host-nodes=1,policy=membind,id=ram-node0 \ -numa node,nodeid=0,cpus=0,memdev=ram-node0 \ -object memory-ram,size=1024M,host-nodes=2-3,policy=interleave,id=ram-node1 \ -numa node,nodeid=1,cpus=1,memdev=ram-node1 \ -m 1536M There are some minor problems but I'd like to see if there are any problems in the general direction.
