[one-users] can not create a snapshot of the disk (Volatile Disk)

[Alexandr Baranov]

Hi I use Nebula version 4.0.1 + KVM hypervisor. Faced with a problem:
I can not create a snapshot of the disk (Volatile Disk).

$ onevm show 30

To test the performance commands "nevm disk-snapshot". I downloaded and
deployed the image of the Market "ttylinux - kvm". Disk from a virtual
machine deployed with this image - is maintained.

Question: this is a bug or a game developer that is not saved to the disk
type (Volatile Disc)?
