While this fixes the bug, it is still a less the useful error.
virCommandRun() already gives a better error message and we are
overriding it.  I'd prefer:

diff --git i/src/util/sysinfo.c w/src/util/sysinfo.c
index 92c3539..7f0a45b 100644

     cmd = virCommandNewArgList(path, "-q", "-t", "0,1,4,17", NULL);
     VIR_FREE(path);
     virCommandSetOutputBuffer(cmd, &outbuf);
-    if (virCommandRun(cmd, NULL) < 0) {
-        virReportError(VIR_ERR_INTERNAL_ERROR,
-                       _("Failed to execute command %s"),

+    if (virCommandRun(cmd, NULL) < 0)
         goto cleanup;
-    }

     if (VIR_ALLOC(ret) < 0)
         goto no_memory;
