ubuntu安装虚拟磁带库mhvtl的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'><strong>1 下载源码</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
从网站https://sites.google.com/site/linuxvtl2/home#mhvtl-download下载最新版的mhvtl，我下的是最新的mhvtl-2013-10-20.tgz版本。</p>

<strong>2 确保内核版本的一致性</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
确保你的内核开发包和你系统正在运行的内核是一个版本的，因为mhvtl有会编译它编写的一个内核模块，如果内核开发包和你系统正在运行的内核不是一个版本的话，在安装mhvtl中的内核模块的时候是加载不到内核中的，虽然可以通过源码中的include/linux/vermagic.h中的VERMAGIC_STRING修改成与当前PC内核uname -r一致即可，不过不推荐使用。</p>

<strong>3 解压缩源代码</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
tar xvfz mhvtl-2013-10-20.tgz</p>

<strong>4 安装四个包lsscsi,sg3_utils,liblzo2-dev,mtx直接用apt-get install命令安装就可以了</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
apt-get lsscsi sg3_utils liblzo2-dev mtx<br>
没有装liblzo2-dev包在编译mhvtl时会提示找不到文件 lzo/lzoconf.h</p>
