Don't use ERANGE as it doesn't make much sense in the error message.
|
|
|
d76c62 |
Also point out that the reply from qemu was too large which is not
|
|
|
d76c62 |
obvious from the original error:
|
|
|
d76c62 |
|
|
|
d76c62 |
error: No complete monitor response found in 10485760 bytes: Numerical result out of range
|
|
|
d76c62 |
|
|
|
d76c62 |
The new message will read:
|
|
|
d76c62 |
|
|
|
d76c62 |
error: internal error: QEMU monitor reply exceeds buffer size (10485760 bytes)
