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.

There are 2 issues here: First we shouldn't add "1" to the return value of numa_max_node(), since the semanteme of the error message was changed, it's not saying about the number of total NUMA nodes anymore. Second, the value of "bit" is the position of the first bit which exceeds either numa_max_node() or NUMA_NUM_NODES, it can be any number in the range, so saying "bigger than $bit" is quite confused now. For example, assuming there is a NUMA machine which has 10 NUMA nodes, and one specifies the "nodeset" as "0,5,88", the error message will be like: Nodeset is out of range, host cannot support NUMA node bigger than 88 It sounds like all NUMA node number less than 88 is fine, but actually the maximum NUMA node number the machine supports is 9. This patch fixes the issues by removing the addition with "1" and simplifies the error message as "NUMA node $bit is out of range". Also simplifies the comparision in the while loop by getting the smaller one of numa_max_node() and NUMA_NUM_NODES up front. |

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.
