[lu lyt]

Hi
Pls Help me, How to moving disk image from one to new one
in the physical disk by lvm , and not by create new vm & install new system!
beacause i want the contents of old vm disk image same to new vm

eg:
# lvs -o +lv_tags

  LV            VG     Attr   LSize   Origin Snap%  Move Log Copy%
Convert LV Tags
......
  vm-115-disk-1 disk4  -wi-a-  16.00G
     pve-vm-115
  vm-116-disk-1 disk4  -wi-a-  16.00G
     pve-vm-116
......
   data              pve    -wi-ao
808.02G
  root              pve
-wi-ao  96.00G
  swap             pve    -wi-ao   23.00G

as above:
vm-115 is the old vm, and vm-116 is new vm, and the disk img of
vm-116-disk-1 is none file & no system in it!
i want to use vm-116 by moving from vm-115,and vm-115 is also can use it;

I trid this links

image(It's had moving disk image from 115 to 116!)
