Engine specifies cdrom twice, with two different device ids.

{'index': '2', 'iface': 'ide', 'specParams': {'path': ''}, 'readonly': 'true', 'deviceId': '713938ee-bdd0-4a84-80d2-387e3b9e13f4', 'path': '', 'device': 'cdrom', 'shared': 'false', 'type': 'disk'},
{'index': '2', 'iface': 'ide', 'specParams': {'path': ''}, 'readonly': 'true', 'deviceId': 'cab66d14-1e9d-498c-82c3-0ab6545ac2c7', 'path': '', 'device': 'cdrom', 'shared': 'false', 'type': 'disk'}

How reproducible:
always

always == always for this particular VM or for all VMs or…?

for all VMs (at least on my setup)

even a new VM you create?
would you please include engine.log for that attempt?

--- Additional comment from  on 2014-06-19 17:17:12 IDT ---

in engine.log i already posted, i created VM called "minivm" on line 3824, and it failed to run around line 3935

--- Additional comment from Omer Frenkel on 2014-06-22 18:35:01 IDT ---

i have few questions to help me understand the root cause of the issue:
1. when creating the vm, do you select any iso?

2. is this a clean installation or upgrade?
i suspect you have something wrong with your blank template configuration
could you please attach the result of the following db query?

select type,device,is_managed,alias,spec_params from vm_device where vm_id = '00000000-0000-0000-0000-000000000000' order by device;

3. i'm interested to know if the duplicate device created on add vm or run,
can you please attach the result of this query as well? (replace <VM_NAME> with the new vm name):

select device,is_managed,alias,spec_params from vm_device where vm_id = (select vm_guid from vm_static where vm_name='<VM_NAME>') order by device;


thanks!

1. - i don't select any iso, i don't even have iso domain

2. clean install on a new VM

engine=# select type,device,is_managed,alias,spec_params from vm_device where vm_id = '00000000-0000-0000-0000-000000000000' order by device;
 type  | device | is_managed | alias |     spec_params      
-------+--------+------------+-------+----------------------
 video | cirrus | t          |       | { "vram" : "65536" }
(1 row)

3. 
on old vm:
engine=# select device,is_managed,alias,spec_params from vm_device where vm_id = (select vm_guid from vm_static where vm_name='minivm') order by device;
 device | is_managed | alias |     spec_params

                             :   "path" : ""
                             : }
 cdrom  | t          |       | {
                             :   "path" : ""

                             :   "heads" : "1"
                             : }

new vm i just created:

seems not to be happening when *not* using instance types

--- Additional comment from Ilanit Stein on 2014-08-12 12:41:22 IDT ---

Verified on ovirt-engine 3.5-rc1

Created a VM both from template (with attached cd), and instance type (Large).
VM started successfully.

Hi,

This bug is also present on 3.4 and the patch needs to be backported.
This happens when using the blank template for creating a new VMs and modifying the advanced options like attaching a CDROM before booting the first time.

Thank you
