Hello, I get the following error when I try to delete snapshots. I need to clear out some of my older snapshots to free up disk space.

Upgrading to 5.0.4 appears to have solved the issue.

Hello,

I am having the same Problem with 5.0.10. I can't imagine that downgrading to 5.0.4 will help

The Problem occures both when the VM is online or offline (tried online first).

This occures on 2 machines to me in the last 2 days.

Same problem after upgrade to 5.0.10 from 4.0.x. Any progress will mean a lot for me.

Did U try with downgrad to 5.0.4 ?

Please post a screenshot of the snapshot tree where you show which snapshot you're trying to delete, and the "recipe" (.vbox file) of the VM (right click on the VM, select "Show in..."). Is the VM running, saved, paused or completely shut when you're attempting this?

I'm having the same problem deleting snapshots.

VBox Version 5.0.14 r105127

I have attached two (2) files:

1. a screenshot of the snapshot list [inline]
2. the entire .vbox file for the VM

Two snapshots cannot be deleted. They are the last two on the list:
name="4.8.00 68428 UPG (bad.1)"
name="4.8.00 68428 UPG (bad.2)"

I see the same error message when I try to delete the other snapshot, "4.8.00 68428 UPG (bad.2)".

One of the two snapshots cannot be restored:

The .vbox file is attached (with a TXT extention to get past the file-type filter).

A similar problem here with Ubuntu Server 14.04 on x86-64 host and VirtualBox 5.0.10.

The messages shown in my command-line environment: Nothing related to the snapshot deletion was written to VBox.log.

Has anyone created a bug report for this problem yet?

I had tried to delete the snapshot previously while the machine was running and it produced a different error: NS_ERROR_FAILURE with “extended info not available”. Unfortunately, I haven’t saved the message but it looked similarly as https://www.virtualbox.org/ticket/12118.

For the record: My problem was probably caused by the lack of free disk space. After freeing some space, the problem disappeared. However, I cannot tell it was the real reason for sure since there was some amount of time between each step. Still I think VirtualBox should print a better-to-understand message.
