使用虚拟化KVM安装RHEL7系统

检查真实物理机是否支持虚拟化功能
[root@server ~]# grep vmx /proc/cpuinfo
[root@server ~]# grep svm /proc/cpuinfo

安装KVM以及相关的依赖软件包
[root@server ~]# yum -y groupinstall "Virtualization Host"
[root@server ~]# yum -y install virt-{install,viewer,manager}
[root@server ~]# echo "net.ipv4.ip_forward = 1" > /etc/sysctl.d/99-ipforward.conf
[root@server ~]# sysctl -p /etc/sysctl.d/99-ipforward.conf
[root@server ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
注释掉其他信息，并追加以下参数
DEVICE=eno16777736
ONBOOT=yes
HWADDR=00:0C:29:17:9E:2E
BRIDGE=virbr0

[root@server ~]# vim /etc/sysconfig/network-scripts/ifcfg-virbr0
DEVICE=virbr0
TYPE=BRIDGE
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.10.10
NETMASK=255.255.255.0
GATEWAY=192.168.10.1
DNS1=192.168.10.1

[root@server ~]# reboot
[root@server ~]# lsmod | grep kvm
[root@server ~]# ip show virbr0
[root@server ~]# virsh -c qemu:///system list
[root@server ~]# virt-manager
