Description
When I try to delete a snapshot of a VM with an immutable disk, I get the following error:
VirtualBox Command Line Management Interface Version 2.1.2 (C) 2005-2009 Sun Microsystems, Inc. All rights reserved.
0%...10%...20%...30%...40%...50%...60%...FAILED Error: failed to discard. Error message: Medium '/engine/native/vmm/virtualbox/dsl-linux/instances/linux01/linux01/Snapshots/{e639aca4-81b9-4986-a475-3304563db1df}.vdi' is not accessible. Accessibility check was not yet performed
The following script produces this error:
============= zen:test jim$ cat manual.sh /usr/bin/VBoxManage registerimage disk /engine/native/vmm/virtualbox/dsl-linux/vdi/dsl-linux-master.vdi -type immutable
/usr/bin/VBoxManage createvm -name linux01 -register -basefolder /engine/native/vmm/virtualbox/dsl-linux/instances/linux01
/usr/bin/VBoxManage modifyvm linux01 -memory 256 -vrdpport 3390 -hda /engine/native/vmm/virtualbox/dsl-linux/vdi/dsl-linux-master.vdi
/usr/bin/VBoxHeadless -s linux01 &
sleep 20
/usr/bin/VBoxManage snapshot linux01 take base
/usr/bin/VBoxManage controlvm linux01 poweroff
sleep 20
VBoxManage snapshot linux01 discardcurrent -all =============
There seems to be a race condition with this error. If I change the final sleep in the script to "sleep 5", the discardcurrent works every time. With it set to 20, it fails every time.
============= Here is the complete output from running the script (with the sleep set to 20):

=============
The above error occurs on Windows XP, Centos, and Mac OSX. This is a showstopper for me because it prevents be from deleting my VM (except for manually editing the VirtualBox.xml).
BTW, it would be really nice to be able to delete a VM, snapshots and all, with a single command.
