You can also use:

> qm help snapshot

To get a more detailed help.

This is a bug. I suggest you do not use the '-freezefs' option (It has
not effect currently).

There is no extra command for that, but you can use the API, like:

# pvesh get /nodes/<nodename>/qemu/<vmid>/snapshot

Does that help?
