一、同一宿主机内迁移
[root@k-node2 ~]# virsh domblklist win7 目标 源 ------------------------------------------------ vda /var/lib/libvirt/images/win7.qcow2 vdb /vm/test1.qcow2 vdc /vm/test2.qcow2 hdb /root/iso/virtio-win.iso [root@k-node2 ~]# mv /var/lib/libvirt/images/win7.qcow2 /vm [root@k-node2 ~]# ll /vm/win7.qcow2 -rw------- 1 qemu qemu 10739318784 5月 6 13:57 /vm/win7.qcow2 [root@k-node2 ~]# virsh edit win7 修改前 <source file='/var/lib/libvirt/images/win7.qcow2'/> 修改后 <source file='/vm/win7.qcow2'/> [root@k-node2 ~]# virsh start win7 域 win7 已开始
[root@master ~]# mkdir /vm [root@master ~]# ll /tmp/win7.xml -rw-r--r--. 1 root root 4660 May 12 22:37 /tmp/win7.xml [root@master ~]# virsh define /tmp/win7.xml Domain win7 defined from /tmp/win7.xml [root@master ~]# virsh list --all Id Name State ---------------------------------------------------- - centos6.7 shut off - centos6.7-1 shut off - centos6.7-2 shut off - win7 shut off
源主机：
[root@k-node2 ~]# rsync -avSHP /vm/win7.qcow2 [email protected]:/vm/ The authenticity of host '172.16.216.140 (172.16.216.140)' can't be established.

三、不同宿主机之间迁移--使用 virsh migrate命令
源主机
virsh # migrate --domain centos7.1 --desturi qemu+ssh://[email protected]/system --offline --persistent [email protected]'s password: [root@k-node2 ~]# rsync -avSHP /vm/centos7-disk1.qcow2 [email protected]:/vm/ [email protected]'s password: sending incremental file list centos7-disk1.qcow2 1361444864 100% 31.07MB/s 0:00:41 (xfer#1, to-check=0/1) sent 1361611141 bytes received 31 bytes 28665498.36 bytes/sec total size is 1361444864 speedup is 1.00
目标主机：
[root@master vm]# virsh list --all Id Name State ---------------------------------------------------- - centos6.7 shut off - centos6.7-1 shut off - centos6.7-2 shut off - centos7.1 shut off
