Failed to attach iso to VM with ConfigDrive on xen/xcpng

[weizhouapache]

Steps to reproduce the issue

• create network offering with userdata=ConfigDrive
• create a network
• create a vm on the new network
• attach an ISO to the VM

The issue is because there is a ConfigDrive ISO attached to the VM, I cannot attach new ISO.
It works on kvm
