[one-users] unable to attach cdrom to VM in opennebula 4.8

[Anandharaj Subramaniam]

I also interested on this. The current practice that we are doing is shutdown/delete the VM, go to template and add the CDROM device and instantiate VM. By doing this we will have new VM ID and lose the accountability of old VM ID info

Fair enough. Then how does one provide an option to change a CD on a server? For example, I have a Windows server rolled and I need to install software on it that is only available on DVD. How can I change disks on those VMs?
