September 18, 2015 Linux Commentscentos 7安装好KVM之后还要安装虚拟机，通过VNC连接手动安装centos 7虚拟机太麻烦了，所以无人值守安装是做好的。简单记录下。无人值守安装centos 7前提是要安装KVM，并且能手动创建虚拟机。 首先创建centos7.ks.cfg文件 vi /root/centos7.ks.cfg (more…)centos 7安装KVM Cat. September 18, 2015 Linux Comments看到linode都由xen转移到kvm，刚好最近新买了台服务器，就不用xen了，记录一下安装centos 7安装KVM。新安装的centos 7怎么初始化就不说，但是要禁止selinux。
