** Description changed: + =============================================================== + SRU Justification + 1. Impact: openstack cannot use numactl to pin kvm to cpus + 2. Test case: ldd /usr/bin/qemu-system-x86* | grep numa + 3. Regression potential: this causes qemu to be build against libnuma. It should only enable users who wish to use numa to do so, though of course new code will be enabled so unepxected regressions are possible. + =============================================================== + 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.
