Subject: [PATCH] qemu-dm: Fix Raw Block IO Debug Print
Date: Thu, 13 Sep 2007 19:23:59 +0900 [thread overview]
Message-ID: <46E90FBF.6060802@ab.jp.nec.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 271 bytes --]
Hi,
This is a trivial fix for debug print formats of raw block io.
Without this patch, qemu-dm occasionally gets stuck
when a raw io device is inaccessible (eg. CR-ROM doesn't exist).
Regards,
