centos 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

centos 7安装KVM
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。
1 | sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config |
yum安装KVM
1 | yum install kvm virt-manager libvirt virt-install qemu-kvm |
接着就是桥接网卡，将/etc/sysconfig/network-scripts/ifcfg-eth0 改为
1 2 3 4 5 6 | DEVICE=eth0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=none BRIDGE=br0 IPV6INIT=yes |
centos7创建KVM虚拟机提示错误Failed to create chardev
运行systemctl status libvirtd出现如下错误
