Public bug reported:
When running
qemu-system-x86_64 -object memory-backend-file,prealloc=yes,mem-
path=/dev/hugepages/libvirt/qemu,size=4096M,id=ram-node0,host-
nodes=0,policy=bind
I got the following error: "NUMA node binding are not supported by
this QEMU"
Looking at the qemu code, it appears that this means that the package
was built without CONFIG_QEMU being defined. The "host-
nodes=0,policy=bind" functionality is in use in OpenStack, and so it
would be problematic if it is not supported in Ubuntu.
