Hi

Been testing latest 5.1, trying to get all the settings correct so that shapshots will work (VMs with qcow2 disks as I have read). But, I can't seem to get the right combination of file system type (ext4, xfs, etc) and lvm-thin and Bus/Device. All seem to have the options for disk format grayed out (see below).

Also tried to find info in https://pve.proxmox.com/wiki/Storage but couldn't find specifics.

On filesystem like ext4... you can choose the format. On LVM not. Only raw. But don't know what your really mean. On LVM-Thin with RAW (Default) Snapsshots are availlable. RAW with LVM-Thin with snapshots is faster then qcow2 and much more stable if you use livesnapshots with a lot of memory.
 
Sorry - I thought that qcow2 was the only way to get snapshots - that may be old info in the wiki or I misunderstood/misread.
