VB 3.0.8 Phantom Record of Attached CD Image

[Chris Williams]

Environment:

• Linux 2.6.30 host (32-bit)
• VBox 3.0.8 binary version
• Windows XP SP3 or Vista client (32-bit)

Possibly related issue: #3071

Steps to reproduce:

• Start a clean Windows client with no attached CD image
• Attach a CD image (e.g. VBox Guest Additions)
• Close the client using the host window close button and select "Power Off Machine" and "Revert to current snapshot"
• Restart the client. Note that client starts without attached image.
• Attempt to attach the same CD image
• Cannot attach: Virtual Media Manager claims it is already attached (see screen shot)
• Virtual Media Manager will not release the image (reports no error)
• Attaching another image works: does not release the phantom attachment
• Phantom attachment stays until VirtualBox modules are unloaded/reloaded

I have reproduced this several times on Windows XP and Vista clients and with old 3.x VMs and fresh 3.0.8 machines.

I have exactly the same problem.

But only with VirtualBox 3.0.8.

With 3.0.4 I can reattach the VBoxGuestAdditions.iso as many times I want.

• Version: VirtualBox-3.0.8-53138-Linux_x86.run
• Host: Debian GNU/Linux 5.0
• Guest: Windows XP SP3
