【Linux】快速创建KVM虚拟机

yum install virt-manager libvirt libvirt-python python-virtinst libvirt-client virt-install bridge-utils

创建网桥

/etc/sysconfig/network-scripts/ifcfg-br0
TYPE=Bridge
BOOTPROTO=static
IPV6INIT=no
NAME=br0
DEVICE=br0
ONBOOT=yes
NM_Controlled=no
IPADDR=192.168.1.2
NETMASK=255.255.255.0
GATEWAY=192.168.1.1

修改实体网卡，通过网桥联网

/etc/sysconfig/network-scripts/ifcfg-em1

TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
NAME=em1
DEVICE=em1
ONBOOT=yes
BRIDGE=br0

重启网络

service network restart

创建虚拟机

virt-install   --name master  \
                  --memory 8192 \
                  --vcpus 4 \
                  --cpu host \
                  --location /data/kvm/CentOS-7-x86_64-DVD-1810.iso \
                  --disk /data/kvm/openstack-master/centos7.img,size=200,format=raw \
                  --network bridge=br0 \
                  --os-type=linux --os-variant=rhel7.3 \
                  --virt-type kvm \
                  --graphics none \
                  --extra-args='console=ttyS0' \
                  --force

克隆虚拟机

virt-clone -o master -n node1 -f /data/kvm/node1/node1
