how to clone a VM on LVM to another in KVM?

  • 772

On a Debian wheezy i installed KVM for virtualization and install some VMs on it. I use separate LVM disks because of its performance for my VMs disk.

Now i need to clone one of them in new LVM disk. I searched too much for it and i found virt-clone, but unfortunately The virt-clone just clone Vms with disk in files and cannot clone LVM disks. I think it is possible by dd like so:

dd if=/dev/vg_kvm/lv_disk1 of=/dev/vg_kvm/lv_disk2

Is there any more optimize solution? How can i clone my VM which is installed on a LVM disk to a new LVM disk?

    You can use LVM volumes as targets for the copy without a problem 

    virt-clone -o source_system --name new_system --file /dev/vg_kvm/lv_disk2

    should do the trick. It handles the source block device (instead of a file) as well.
