Forgot this: rhevm-4.1.6.2-0.1.el7.noarch (Originally by Germano Veit Michel) Just finished the analysis for 2 VMs. Here are some more detailed logs. The ones in comment #0 are incomplete as it was 3 disks instead of 1.

Could you take a look, please? Thanks! (Originally by Allon Mureinik) Hi, I could not find the root cause for this problem, maybe the UI exceptions messed with the parameters sent. In any case, I can reproduce via REST API by providing a disk from another VM in the restore request. I will add a validation in the command to avoid this issue. (Originally by Fred Rolland) Hi Fred, That sounds good enough to prevent what the customer hit, you will also be preventing any incorrect API usage to break the VMs. Can you still get this to 4.1.z? As we don't really know what caused the issue (likely the misbehaving UI on Safari?) and the customer is a bit worried it may happen again (I think it's unlikely though). Thank you. (Originally by Germano Veit Michel) Verified using: ovirt-engine-4.1.9.1-0.1.el7.noarch vdsm-4.19.45-1.el7ev.x86_64 Scenario tested: 1. Created 2 VMs with snapshots. 2. Try to preview a snapshot of VM1 with a disk from VM2 using REST-API Result: Operation is blocked.
