VirtualBoxVM hangs when choosing a CD/DVD device

[Mac Lake]

Hi,

whenever I try to choose a virtual CD/DVD disk file or the physical drive with Windows 7 as guest and Mac OS X 10.7 host, both VIrtualBoxVM and VirtualBox hang: The Windows mouse pointer freezes, but there’s the spinning beach ball (by Mac OS X) which is still moving, but VirtualBox and VIrtualBoxVM and thus Windows don’t react any more. I can only kill VIrtualBoxVM, then VirtualBox operates again. The same applies for “Install Guest Additions…”, which also tries to mount the corresponding ISO file.

So I can’t install the guest additions or mount any physical CD/DVD or disk image.

With Linux (Ubuntu and Knoppix) as guest systems mounting CD/DVD drives works without any problem.
Edit: Now I don’t get an error message in Ubuntu, but I can’t access the disks (VEBR_PDM_MEDIA_LOCKED), and in Knoppix I have the same problem like in Windows. So maybe the problem is not Windows guest specific.

Is there any way I can fix this? Should I file a bug report?

I'm experiencing this exact same issue

Hi,
While I realise this is the wrong forum, its the right thread. I have a Centos6 guest running
on Mac OSX6 and I have the same issue of the whole VM hanging if I try to mount or unmount
a CDROM while the machine is running. I have installed the guest editions by having the iso
in a virtual CD drive a boot time, but I try to unmount that disk the VM hangs. If I try
and simply mount it once the machine is running the VM hangs. Force quit is the only solution.

I have regularly been tripped up with the choose CD dialog appearing to crash (in fact just a very long timeout) when one or more of the recently used items is no longer available.

I use ISO images from a few different networks & so the MRU list sometimes has a network or removable mount (eg, usb key) device is no longer present the next time I try to change the mount.

This doesn't affect existing ISO mounts working, only the attempt to change it in the GUI.

Going into the VirtualBox.xml file [when it is not running] and removing inaccessible items from <ExtraDataItem name="GUI/RecentListCD" /> value attribute fixes the problem.
Expected behaviour (the dropdown of choices including local drives, vbox additions & "choose iso") is restored.
