Comment 2 Pavel Novotny 2014-02-10 17:25:57 UTC 
Verified in rhevm-3.3.1-0.47.el6ev.noarch (is34).

Changing CD permanently on a running VM via REST API is now possible.

Verification steps:
1. Have a running VM without CD-ROM image attached (I used Fedora 19).
2. Attach CD permanently:
>>> request:
PUT /api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8/cdroms/00000000-0000-0000-0000-000000000000

<cdrom>
<file id="CentOS-6.5-x86_64-minimal.iso"/>
</cdrom>

>>> response:
<cdrom href= "/api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8/cdroms/00000000-0000-0000-0000-000000000000" id="00000000-0000-0000-0000-000000000000">
<vm href= "/api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8" id="5d4f3c8a-7514-400d-a0f7-5c6c51178ba8"/>
<file id="CentOS-6.5-x86_64-minimal.iso"/>
</cdrom>

3. Verifying that change is permanent:
>>> request:
GET /api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8/cdroms/00000000-0000-0000-0000-000000000000

>>> response:
<cdrom href="/api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8/cdroms/00000000-0000-0000-0000-000000000000" id="00000000-0000-0000-0000-000000000000">
<vm href="/api/vms/5d4f3c8a-7514-400d-a0f7-5c6c51178ba8" id="5d4f3c8a-7514-400d-a0f7-5c6c51178ba8"/>
<file id="CentOS-6.5-x86_64-minimal.iso"/>
</cdrom>

The CD-ROM is not changed on-the-fly while the VM is running, but it's permanent and applied after the VM is stopped & started again.

Additional Notes:

The ';current' matrix parameter works still the same: it changes the CD on-the-fly, but the change doesn't survive after the VM is stopped.
