我正在一台较旧的 Vernonia 服务器上安装 XENCloverdale VT-d 兼容CPU，无论是S5000XVNSATAR或者S5000XVNSASR， A2006年设计和一些文档仍然可用。 Intel 中未发现此问题社区支持论坛[替代搜索]。
model name : Intel(R) Xeon(R) CPU X5365 @ 3.00GHz
Base Board Information
Manufacturer: Intel
Product Name: S5000XVN
Version: Not Specified
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
我已经验证Intel VT-d在enabledBIOS 中
我已经安装xen-system-amd64并克隆了现有（功能）XEN VM 逻辑卷，并添加了（修改后的）server.cfg 文件。
然而，当我尝试启动虚拟机时，我得到......
