KVM | centos 安装 window 虚拟机
环境： CENTOS 7.3
1. 准备
1.1 检查是否支持虚拟化
cat /proc/cpuinfo | egrep 'vmx|svm'
要求结果中返回相关字段
1.2 关闭 selinux
vi /etc/sysconfig/selinux
要求SELINUX=disabled
2. 安装
yum -y install qemu-kvm qemu-kvm-toolsyum -y install libvirt python-virtinst libvirt-python virt-manager libguestfs-tools bridge-utils virt-install
2.1 加载 KVM
lsmod | grep kvm
kvm_intel 170181 0
kvm 554609 1 kvm_intel
irqbypass 13503 1 kvm2.2 启动 KVM
systemctl start libvirtd.service
systemctl enable libvirtd.service
systemctl status libvirtd
systemctl is-enabled libvirtd 2.3 搭建网桥
将原有网卡的配置备份一份，然后进行修改
物理网卡的配置ifcfg-eth0
DEVICE=eth0
BRIDGE=br0 #指向网桥br0
ONBOOT=yes
TYPE=Ethernetifcfg-br0网卡配置
TYPE=Bridge
DEVICE=br0
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=10.24.18.151
GATEWAY=10.24.18.254
NETMASK=255.255.255.128因为我这是同时连接了2个网段，因此还会设置eth2和br2,区别就是，网关只能在一个口上设置。
systemctl restart network.service后即可。brctl show可以看到网桥名字
2.4 安装 VNC 环境
yum -y install tigervnc tigervnc-server
virt-install --name $name --ram $ram --vcpus=$cpu --disk path=$img,size=$sizeG --network bridge=$eth --os-type=windows --os-variant=$os --cdrom $iso --vnclisten=$ip --vncport=$port --vnc--name: 虚拟机名称
--ram：虚拟机内存
--vcpus：虚拟机 CPU 个数
--cdrom：从本地安装
--disk: 生成的磁盘文件路径，以及磁盘大小
--network：网络模式，默认为 nat
或直接拷贝现有的配置文件/etc/libvirt/qemu/目录下xml文件。

3 win_2008 running
5 win8_8_200 running然后就可以通过vnc viewer来远程访问这个window了，进去之后配置网卡等或管理BMC
virsh shutdown win8_8_200用于关闭virsh start win8_8_200 用于启动virsh destroy win8: 销毁虚拟机virsh undefine win_2008 从列表中删除
