# 1  

I want to change my virtual box disk to immutable. When I try to do that I get the following error.

Error changing medium type from Normal to Immutable.
Cannot change the type of medium '/root/VirtualBox VMs/fedora13/fedora13.vmdk' because it is attached to 1 virtual machines
Please help me how to resolve this. My host system is RHEL 5.6

Open the Virtual Media Manager, "release" the affected image and try again.
The Virtual Media Manager allows you to

    remove an image from the registry (and optionally delete the image file when doing so);

    "release" an image, that is, detach it from a virtual machine if it is currently attached to one as a virtual hard disk.
