You can use the 'virDomainBlockCopy' API to achieve this. To use it via virsh, the simplest way would be to: virsh blockcopy $VMNAME $DISKTARGET --dest /path/to/destination --transient-job --pivot (--verbose) ($DISKTARGET is 'vda' for example) In case you need a more complicated description of the target of the copy such as a network storage target you can also use the --xml option to use a XML description of the target. > I found the live migration is not allowable on the same host using > virsh. Is there any suggestion or better practices for this? Full migration would also try to move the qemu process which is not required in your case.
