报错如下：</p>

通过查资料发现，virt-install可以开debug模式的，加入--debug选项即可</p>

<p>
这里就可以看出问题了，明明是64位的操作系统，为什么去找./install/netboot/ubuntu-install/i386/linux的路径</p>
<p>
我们去看看iso文件中正确的路径是什么：</p>

<strong>3.修改virt-manager代码：</strong></p>

通过上面的报错，发现virt-manager使用python写的！正好想看什么源码来自，这个正好！</p>

<p>
发现基于Debian的系统，__init__方法中self._treeArch初始化时是i386，估计是virt-manager读取ubuntu的iso文件时，出了什么问题，没读出该系统是x86_64类型，将该值改为amd64,就可以了。</p>
<p>
再次运行virt-install，成功进入ubuntu安装界面！</p>
<p>
<strong><span>附：CentOS命令行使用KVM安装64位ubuntu报"Couldn't find hvm kernel for Ubuntu tree."的解决办法</span></strong></p>
<p>
grep -n -A21 'class DebianDistro' /usr/lib/python2.6/site-packages/virtinst/OSDistro.py 命令可以查看DebianDistro类的__init__方法</p>
