Don't use ERANGE as it doesn't make much sense in the error message. Also point out that the reply from qemu was too large which is not obvious from the original error: error: No complete monitor response found in 10485760 bytes: Numerical result out of range The new message will read: error: internal error: QEMU monitor reply exceeds buffer size (10485760 bytes) Signed-off-by: Peter Krempa <pkrempa@redhat.com> --- src/qemu/qemu_monitor.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index ccd20b3740..e3bd000ccb 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -484,9 +484,9 @@ qemuMonitorIORead(qemuMonitorPtr mon) if (avail < 1024) { if (mon->bufferLength >= QEMU_MONITOR_MAX_RESPONSE) { - virReportSystemError(ERANGE, - _("No complete monitor response found in %d bytes"), - QEMU_MONITOR_MAX_RESPONSE); + virReportError(VIR_ERR_INTERNAL_ERROR, + _("QEMU monitor reply exceeds buffer size (%d bytes)"), + QEMU_MONITOR_MAX_RESPONSE); return -1; } if (VIR_REALLOC_N(mon->buffer, -- 2.24.1
