X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: ehabkost@redhat.com, he.chen@linux.intel.com Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" When using following CLI: -numa dist,src=128,dst=1,val=20 user getsi a rather confusing error message: "Invalid node 128, max possible could be 128" Where 128 is number of nodes that QEMU supports (MAX_NODES), while src/dst is an index up to that limit, so it should be MAX_NODES - 1 in error message. Make error message to explicitly state valid range for node index to be more clear.
