<br>
"""<br>
Requirements<br>
<br>
In order to use Proxmox VE live snapshots all your virtual machine disk images must be stored as qcow2 image or be in a storage that supports live snapshots and is managed by Proxmox (like Ceph’s RADOS Block Device (RBD)). Future version will support also Sheepdog or Nexenta.<br>
<br>
Difference between LVM snapshots and Live snapshots<br>
<br>
LVM snapshots are used for doing backups. Live snapshots are used to preserve the state of KVM virtual machine.<br>
"""<br>
<br>
So we are confusing "LVM Snapshots" with "Live snapshots" don't you think? :)<br>
<br>
They both have different requirements and different goals...<br>
