[Feature]: Thin provisioning disks

[EHRETic]

Is your proposal related to a problem?

The only problem is backup size because of big Docker volumes 😊 (probably, this feature would be nice on Windows & mac)

Describe the solution you'd like.

The ability to choose between thin provisioning disks and fat ones at VM creation

Describe alternatives you've considered.

Worth a try, thanks in advance
