centos7 安装XEN失败求助

5
已采纳

服务器 PowerEdge R610
CPU:双路 Xeon E5620
内存:16G
系统安装ISO:CentOS-7-x86_64-Minimal-1804.iso
安装系统后操作

yum install bash-completion -y
yum install bzip2 bzip2-devel zlib-devel sqlite-devel
yum groupinstall development tools
yum install cmake ncurses ncurses-devel -y
yum install epel-release
yum install centos-release-xen
yum update #这里会更新内核到 Linux 4.9.127-32.el7.x86_64
yum install xen

然后重启后,进系统在有 Xen hypervisor 字样的启动项就无法进系统,会自动重启
而在没有 Xen hypervisor 启动项是可以正常进系统的,下面是系统自动生成的grub.cfg ,求高手帮忙分析原因
还有,我在自己家的电脑试的时候,使用同样的步骤是可以正常进入系统,所不同的家里的电脑使用的安装是 CentOS-7-x86_64-LiveGNOME-1708.iso
