Previously, if smartcard support was enabled on a template, every time when the template was edited and saved, a new smartcard entry was created. This eventually caused virtual machines to fail to boot. With this update, only one smartcard device is available for templates that have smartcard support enabled.
Description of problem:
If smartcard support is enabled in a template, every time the "Edit" window is opened and "OK" is pressed a new smartcard entry is created.
Even if no changes were made to the template, if "OK" is pressed, a duplicate is added.
Since qemu does not handle multiple smartcards, any VM created from a template with more than one smartcard will fail to boot.
Version-Release number of selected component (if applicable):
rhevm-3.3.2-0.50
How reproducible:
100%
Steps to Reproduce:
1. Create a template (I used win2k8)
2. Enable smartcard support in the template
3. Edit the template, make no changes, and press "OK"
Actual results:
Duplicate smartcard entrries are created
Expected results:
The single smartcard device is persisted, but no new ones are added.
Additional info:
* Initial template with no smartcard(ID a11f8bb7-529f-472e-8296-052e689ae0d7)
engine=# select count(*) from vm_device where type = 'smartcard' and vm_id = 'a11f8bb7-529f-472e-8296-052e689ae0d7';
count
-------
0
* Edit the template, add smartcard support ("Show Advanced Options" -> Console -> Smartcard Enabled)
engine=# select count(*) from vm_device where type = 'smartcard' and vm_id = 'a11f8bb7-529f-472e-8296-052e689ae0d7';
count

* Edit the template again, but make no changes. Just click "OK"
engine=# select count(*) from vm_device where type = 'smartcard' and vm_id = 'a11f8bb7-529f-472e-8296-052e689ae0d7';
count

* Repeat 4 more times
engine=# select count(*) from vm_device where type = 'smartcard' and vm_id = 'a11f8bb7-529f-472e-8296-052e689ae0d7';
