Allocated memory - Reserved memory = Size of vswp

At the moment:

2gb - 0b = 2Gb

You either need to decrease the allocated memory or increase the memory reservation.

But, if you’re that short on disk space that you need to do this, you don’t have a big enough disk.

There are other files associated with every VM beyond the virtual disk - the 2Gb memory allocation will have resulted in the creation of a .vswp file of just over 2Gb in size when you powered on the VM (unless you had set a memory reservation).

Your storage requirement will increase further if you use VM snapshots.

vswap file is there where you allocated memory 2 GB that the reason showing total 17 GB 15 GB disk + 2 GB memory. I see Scott already describe you about vswap and memory reservation.
