xen的domainU启动失败
操作系统是redhat5.2，xen是3.x版本
我今天采用复制domain0的方式安装了一个domainU，启动的时候出现了如下错误，怎么回事呢？

貌似是半虚拟的kernel问题，dom0的kernel在domU有问题，具体可能性很多
不行就换全虚拟吧
我在系统中用yum groupinstall virtualization之后用xen的kernel启动，进入系统，在domainU的配置文件中kernel=“/boot/vmlinuz-2.6.18-92.el5xen”。会是这里的问题吗？
恩，这就是半虚拟，简单的办法就是换全虚拟
为什么会这样啊？半虚拟化就很有可能启动不了吗？我已经搞了一天了，都搞晕了。
能说清楚点吗兄弟？
简单来说，如果你用 redhat 半虚拟 suse9，就会有那问题，因为 suse9 默认的文件系统是 reiserfs，redhat 的内核不支持。我的建议是你重装一个虚拟机，用 virt-manager，装的时候主要选择 hvm（全虚拟），就不用有我说的类似问题了
libc.so.6 的问题吧！好像遇到过，更新一下。
在启动的过程中竟然有那么多的 permission deny，为什么会这样呢？
我用的系统是 rhel5.2，guest 也是 5.2。
我觉得复制 domain0 的文件没有问题，mkinitrd 也没有问题，并且 domainU 的配置文件应该也没有问题，不然不能启动到那个地方。
问题解决了，将guest里边的selinux禁用就可以了。
vim etc/sysconfig/selinux，将selinux设置为disable就可以了。
