1.1.2 配置KVM环境



[[email protected] ~]# yum install libvirt* virt-* qemu-kvm* -y


[[email protected] ~]# virsh iface-bridge eth1 br1 
使用附加设备 br1 生成桥接 eth1 失败
已启动桥接接口 br1

1.1.3 导入虚拟机


[[email protected] ~]# systemctl start libvirtd.service
[[email protected] ~]# systemctl enable libvirtd.service


[[email protected] ~]# virt-v2v -i ova centos-dev-test01-v2v.ova -o local -os /vmhost/dev/dev-test01  -of qcow2 
[   0.0] Opening the source -i ova centos-dev-test01-v2v.ova
virt-v2v: warning: making OVA directory public readable to work around

导入完成后在 /vmhost/dev/dev-test01 目录下会生成文件

[[email protected] dev-test01]# pwd
[[email protected] dev-test01]# ls
centos-dev-test01-v2v-sda  centos-dev-test01-v2v.xml


修改网卡source network 为桥接

1.1.4 启动虚拟机


[[email protected] dev-test01]# virsh  define centos-dev-test01-v2v.xml  
定义域 centos-dev-test01-v2v(从 centos-dev-test01-v2v.xml)


[[email protected] dev-test01]#  virsh list --all 
 Id    名称                         状态
 -     centos-dev-test01-v2v          关闭


[[email protected] dev-test01]#  virsh start centos-dev-test01-v2v 
域 centos-dev-test01-v2v 已开始

1.1.5 测试可用性


[[email protected] ~]# ssh [email protected]
