Comment 2 vvyazmin@redhat.com 2012-08-02 08:07:34 UTC 
No, they have different scenario, different exceptions, but have same symptoms.
Comment 4 vvyazmin@redhat.com 2012-08-02 10:56:47 UTC 
Already speak with Liron Aravot, he see different code solution, for those 2 bugs
Comment 5 vvyazmin@redhat.com 2012-08-02 10:57:47 UTC 
Same error when you do following scenarios:


1. Create VM with bootable, Thin-Provision disk on iSCSi SD
2. Power-on VM
3. Create a new (floating) disk Thin-Provision on same iSCSi SD
4. Add disk (from step 3) to current running VM (from step 2)
5. Deactivate disk (from step 3)
6. Remove disk (from step 3), and select check-box "Remove permanently"
