It's a Workstation 14 Pro, and the issue happens only with this virtual machine (or, better, with this virtual disk, see later).

I tried to clone other VMs, and it works.

The VM itself works. It starts, it shuts down etc. vmdk is single file, not preallocated. "Defrag" and "Compact" return no error.

But when I try to clone it I get this error. Both from specified snapshot and current state. In the end, I tried to delete all snapshot and now I have none of them, only current state. I got no error during snapshot deletion / consolidation phase.

I'm trying a full clone.

I also tried to delete VM, create another and mount the same disk: it fails again to clone, so it seems that the issue is inside vmdk and not in VM config.

vmware.log is untouched at the time of cloning attempt, and inside ui-log in /tmp/ I find these lines:
