(3.1.0) VBoxManage not able to delete snapshots

[kmrdeva]

Hi all,

Have just installed VB 3.1.0 on my Windows 2003 host and found a problem (hope I'm not doing it wrong). Is anyone facing the same issue?

Guest Name : VB0S1
Snapshot Names : OS120091201, OS120091202, OS120091203

I've successfully taken snapshots via VBoxManage, but am having trouble deleting them via the cmd line tool. Deleting via the VB UI is working ok.

Taking snapshots (OK):

vboxmanage snapshot VB0S1 take OS120091201

Deleting snapshots (ERROR):

vboxmanage snapshot VB0S1 delete OS120091201

i have the same problem except the fact that i can not delete the snapshots not even from GUI.

in my case a have a VM with 3 cascading snapshots and i can`t delete any of them.

Same thing here (vboxmanage and GUI)! I can't even delete the snapshots I've just made one second before with v3.1.0 (Running under WinXP SP3).

This is obviously an important bug!

I've posted a bug report on the public bugtracker. Ticket #5727

the problem is still present in 3.1.2

I also have this problem. I can delete snapshots in the GUI, but not using vboxmanage. Since I use a script running vboxmanage to do nightly backups of my VM, a speedy resolution would be much appreciated - thank you!

I seem to only encounter this problem if there is an attached write-through disk in the snapshot. Anyone have a problem with just an immutable disk attached?

I do not use a write-through disk but still have the same problem.

I do not use a write-through disk but still have the same problem.

My setup has no write-through disks, same problem though..

[r0lZ]

I have some writethrough discs too, but even when I mount only a single normal disc, I cannot delete the snapshots.

Not sure if it's related to this bug, but I've also noticed that it is impossible to unmount a CD drive. Seems that when you attach something to a vobx, you can never get rid of it!

As nobody seems to take care of this bug, I guess we have to downgrade to a more stable version...

It's free software ... ask nicely ... be happy for what's available already!

I use VirtualBox 3.1.6 and I have a similar problem: VBoxManage is not able to delete snapshots using the snapshot name but it can delete them using the UUID.

The UUID can be found in one of two ways:
1) using the VBoxManage "showvminfo" command,
2) looking for the name of the .sav file in .VirtualBox/Machines/<vmname>/Snapshots

So, here is the workaround:

VBoxManage snapshot Myvmname take test-snap --description test-snapshot

...do what you need with the snapshot, then delete it

VBoxManage controlvm Myvmname acpipowerbutton
VBoxManage snapshot Myvmname delete `ls /home/vmadmin/.VirtualBox/Machines/Myvmname/Snapshots/*.sav | sed -e 's/.*{\(.*\)}.*/\1/'`

Hope it helps.
