Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

On some of the NUMA platforms, the CPU index in each NUMA node grows non-consecutive. While on other platforms, it can be inconsecutive, E.g. % numactl --hardware available: 4 nodes (0-3) node 0 cpus: 0 4 8 12 16 20 24 28 node 0 size: 131058 MB node 0 free: 86531 MB node 1 cpus: 1 5 9 13 17 21 25 29 node 1 size: 131072 MB node 1 free: 127070 MB node 2 cpus: 2 6 10 14 18 22 26 30 node 2 size: 131072 MB node 2 free: 127758 MB node 3 cpus: 3 7 11 15 19 23 27 31 node 3 size: 131072 MB node 3 free: 127226 MB node distances: node 0 1 2 3 0: 10 20 20 20 1: 20 10 20 20 2: 20 20 10 20 3: 20 20 20 10 This patch is to fix the problem by using the CPU index in caps->host.numaCell[i]->cpus[i] to set the bitmask instead of assuming the CPU index of the NUMA nodes are always sequential. |

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
