List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: ehabkost@redhat.com, drjones@redhat.com When using following CLI: -numa dist,src=128,dst=1,val=20 user gets 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.
