When using following CLI:
|
|
|
357786 |
-numa dist,src=128,dst=1,val=20
|
|
|
357786 |
user gets a rather confusing error message:
|
|
|
357786 |
"Invalid node 128, max possible could be 128"
|
|
|
357786 |
|
|
|
357786 |
Where 128 is number of nodes that QEMU supports (MAX_NODES),
|
|
|
357786 |
while src/dst is an index up to that limit, so it should be
|
|
|
357786 |
MAX_NODES - 1 in error message.
|
|
|
357786 |
Make error message to explicitly state valid range for node
|
|
|
357786 |
index to be more clear.
