在Fedo8中使用xen安装guest OS遇到的问题

我在使用virt-manager时遇到了下面的问题，安装终止。请问这是什么意思，有什么解决方法？

弹出窗口报警如下：
Unable to complete install: 'virDomainCreateLinux() failed POST操作失败: (xend.err 'Device 51712 (vbd) could not be connected.\nFile /xen/Fedo/fedo8.img is loopback-mounted through /dev/loop0,\nwhich is mounted in the privileged domain,\nand so cannot be mounted by a guest.')'
点击detail时，具体信息如下：
Unable to complete install '<class 'libvirt.libvirtError'> virDomainCreateLinux() failed POST操作失败: (xend.err 'Device 51712 (vbd) could not be connected.\nFile /xen/Fedo/fedo8.img is loopback-mounted through /dev/loop0,\nwhich is mounted in the privileged domain,\nand so cannot be mounted by a guest.')

顺便说一下，我是尝试用映像文件的方式来安装guestOS的

我用的是 virtualbox 安装的 XP。没用过 XEN

主要用来上网上银行。
