Remount recently unmounted media does not mount it => Fixed in SVN

[Sasquatch]

If you unmount an ISO from the Guest, you can't mount it again for a while. You usually have to shutdown the VM before the actual ISO is in released state, or wait a long time (an hour or more). When selecting an ISO image from the Media Manager, it will show it's state as 'attached', while the Disc Icon in the VB GUI doesn't reflect this. If a different ISO is mounted, it works, but then both ISOs are shown as mounted and as soon as the second ISO is unmounted, it too cannot be mounted again.

A probably related issue is when installing an OS (tested with Linux) that 'ejects' it's media after installation, you can't boot from it again until you shutdown the VM.

Which host is that? Can you provide a VBox.log file of such a session when mounting an ISO didn't work? We cannot reproduce the problem.

[Sasquatch]

This is with Xubuntu 8.10. I didn't see anything relevant in the logs. Will check to make sure. It happens on both my PC and laptop, though they share the same VMs and settings.

After the VM has run, you can't release the already released ISO. You get the message if you really want to detatch <file> from <machine>. After hitting OK, it's still marked as attached to the machine. All ISO images do this, but just tested it again with the GA. There is no mentioning in the log files of an attachment of the ISO, nor detaching it.

Even after closing all VB related processes. There is no mentioning of the ISO being mounted anywhere. After a few minutes, the ISO is released, if the VM is no longer running. I don't know exactly how long it takes if the VM keeps running.

I have seen this on VB 2.1.4 with a Linux host, Windows XP guest using VBoxManage:

[vboxuser ~/atf-scripts/sandbox/windows]$ VBoxManage controlvm jla0 dvdattach ~/atf-scripts/sandbox/windows/sandbox.iso VirtualBox Command Line Management Interface Version 2.1.4 (C) 2005-2009 Sun Microsystems, Inc. All rights reserved.

[vboxuser ~/atf-scripts/sandbox/windows]$

I then used the ISO from the guest. and then: [vboxuser ~/atf-scripts/sandbox/windows]$ VBoxManage controlvm jla0 dvdattach none VirtualBox Command Line Management Interface Version 2.1.4 (C) 2005-2009 Sun Microsystems, Inc. All rights reserved.

[vboxuser ~/atf-scripts/sandbox/windows]$

I modified the iso image using mkisofs, then

[vboxuser ~/atf-scripts/sandbox/windows]$ VBoxManage controlvm jla0 dvdattach ~/ atf-scripts/sandbox/windows/sandbox.iso VirtualBox Command Line Management Interface Version 2.1.4 (C) 2005-2009 Sun Microsystems, Inc. All rights reserved.

which is weird because I provided the full path to the ISO, which is what's contained in the xml file, but the error message only contains the basename of 'sandbox.iso'.

Further attempts give different errors:

Note that the UUID is all 0's.

A fix related to mounting/unmounting was committed to SVN which very much looks like it could fix this report. Please reopen if necessary.

How long ago was this fix put in? Is it included in 2.2.0?

[Jens]

Reopen as long as a version with this fix is not officially released (simply to handle this report like we handle all others).

[Jens]

This fix was put in just today and is expected to be in 2.2.

[Jens]

FYI, it should be fixed with r18210 and later of the OSE. In case you want to compile it, we'd be interested in your feedback.

Unfortunately, the server that I'm running VBox on runs in headless mode without X even installed, so I rely on the RDP functionality that is not present in the OSE edition.
