Description of problem: When Creating a vm from template with template provisioning:Thin, there is no need to choose disks allocation policy because the engine performs image snapshot by default. generally,this menu is very complicated and confusing. Version-Release number of selected component (if applicable): vdsm-4.14.7-3.el6ev.x86_64 rhevm-3.4.0-0.21.el6ev.noarch How reproducible: 100% Steps to Reproduce: Setup:have dc with 2 domains(one nfs,one iscsi) 1.create vm+disk,make template 2.copy template to the other domain 3.add new vm->choose the template->advance options->Resource allocation->choose thin template provisioning Actual results: A user can "play" with the allocation policy window but it has no meaning(see image) Expected results: the disks allocation policy should be greyed out for template thin provisioning.

Disk format selection should be disabled on thin provisioning. Already fixed on: http://gerrit.ovirt.org/#/c/28079/
Created attachment 899578 [details] image guys, there's another option which is redundant in this scenario,(view image). choosing create as clone with provisioning policy:"thin" should be greyed out as well!

For block domains, cloning a COW disk is applicable with thin format; hence the option is still needed. Making sure that the result format is reported correctly should be covered in bug 1101011.
Created attachment 900300 [details] image taken from ui,raw preallocated iscsi template Hi Erez, we actually discussed that yesterday, well you are right of-course, but I don't see a reason why this option is already disabled when creating a template from raw preallocated iscsi disk(please see image), but appears when the template is on both domains (mind that the iscsi part is also raw preallocated), if COW disk is applicable with thin format,so it should be appeared on cloning menu in the case of both a template made out of raw preallocated and copied from nfs, don't you think?
