Nijin, does this reproduce without the "async=True"?

Eyal - this fix was backported (incorrectly) without the bug being cloned.
Can you please add it to ET for 4.1.2 (it's part of ovirt-engine-4.1.2.2)?
Comment 8 Israel Pinto 2017-05-14 16:52:51 UTC 
Verify with:

Steps with REST API:
1. Create snapshot with/without memory
2. Remove snapshot with async=True
DELETE request content is --  url:/ovirt-engine/api/vms/ef2fc720-7905-4231-9949-68296a05b501/snapshots/b3f87241-9ed5-4dcf-8057-7513f8a7dd1c 
<action>
    <async>true</async>
    <grace_period>
        <expiry>10</expiry>
    </grace_period>
</action>

Results: 
Snapshot deleted in both cases
