1.1.2 配置KVM环境



[root@clsn7 ~]# yum install libvirt* virt-* qemu-kvm* -y


[root@clsn7 ~]# 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


[root@clsn7 ~]# systemctl start libvirtd.service
[root@clsn7 ~]# systemctl enable libvirtd.service


[root@clsn7 ~]# 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

[root@clsn7 dev-test01]# pwd
[root@clsn7 dev-test01]# ls
centos-dev-test01-v2v-sda  centos-dev-test01-v2v.xml
