KVM 虚拟机 安装配置

#####安装配置KVM
egrep ‘(vmx|svm)‘ /proc/cpuinfo #验证CPU是否支持KVM

#yum安装软件包
yum install  kvm virt-*  libvirt  bridge-utils qemu-img qemu-kvm-tools -y
#yum -y install tunctl
#补充安装kvm虚拟化一些管理工具包
#yum install libguestfs-tools -y
#加载kvm 内核
modprobe kvm
modprobe kvm-intel
modprobe -ls | grep kvm #查看内核
lsmod | grep kvm

#配置网络桥接
mkdir /it/netbak -p
cp /etc/sysconfig/network-scripts/* /it/netbak/
#网卡名eno1为例
cd /etc/sysconfig/network-scripts
cp ifcfg-eno1 ifcfg-br0
#ifcfg-eno1 修改，注释掉IP、GATEWAY、NETMASK
sed -i ‘s/^IPADDR=/#IPADDR=/g‘ ifcfg-eno1
sed -i ‘s/^GATEWAY/#GATEWAY/g‘ ifcfg-eno1
sed -i ‘s/^IPADDR=/#IPADDR=/g‘ ifcfg-eno1
echo BRIDGE="br0">>ifcfg-eno1
#ifcfg-br0 修改，改名称、驱动绑定
sed -i ‘s/TYPE="Ethernet"/TYPE="Bridge"/g‘ ifcfg-br0
sed -i ‘s/DEVICE="eno1"/DEVICE="br0"/g‘ ifcfg-br0
sed -i ‘s/NAME="eno1"/NAME="br0"/g‘ ifcfg-br0
sed -i ‘s/^UUID=/#UUID=/g‘ ifcfg-br0
sed -i ‘s/^HWADDR=/#HWADDR=/g‘ ifcfg-br0

systemctl restart network #重启网络
ifconfig

#开启kvm，设置开机启动
systemctl restart libvirtd
systemctl enable libvirtd
