yum install -y qemu-kvm libvirt

yum install -y virt-install

systemctl start libvirtd

 

2、创建一个虚拟机磁盘

qemu-img create -f qcow2 /tmp/centos7.2.qcow2 10G

 

3、安装一台虚拟机

virt-install --virt-type kvm --name centos --ram 1024   --disk /tmp/centos7.2.qcow2,format=qcow2   --network network=default   --graphics vnc,listen=0.0.0.0 --noautoconsole   --os-type=linux --os-variant=centos7.0   --location=/tmp/CentOS-7-x86_64-DVD-1511.iso

4、启动

virsh list --all

virsh start centos7.2

5、安装默认需要的软件

net-tools   tree scree wget  git   vim salt-minion zabbix-agent  lrzsz

6、修改网卡
