vbox can't delete dvd image that is not accessable

[Leonid Evdokimov]

When I start VirtualBox I see following:

Invalid image file path: '/mnt/cdrom/winxp-sp2-en.iso' (VERR_ACCESS_DENIED).

Result Code: 0x80004005
Component:   DVDImage
Interface:   IDVDImage {140fff03-e479-4194-8562-abc4f8171009}

Ok, I unmounted /mnt/cdrom that was NFS share and now /mnt/cdrom/ is drwx------ root:root, but I don't need the image anymore, let's try to unregister it from command line...

darkk@thinkpad ~ $ VBoxManage unregisterimage dvd /mnt/cdrom/winxp-sp2-en.iso

Oops, seems my vbox is broken until admin comes back. ;)
