What happened?

When attempting to snapshot a VM without a hard disk an error is thrown.
Skip VM problem storage space out of 95%

When a disk exists, whether attached or not, it works fine. As you can see below I also have enough space available.
A VM without a disk is very rare thing, of course, but since this works perfectly fine via the proxmox GUI I consider this a bug.

Expected behavior

A snapshot should be possible even without a disk attached.

Relevant log output

Hi,
Why vm without disks? You can exclude using "-104" from the vmid parameter.

Best regards

This particular VM is mostly used for testing various live distributions. I wanted to still be able to easily revert to older VM settings.
It took me a minute to figure out how to build this but it works fine. Thanks!
