If template exists in more then one storage domain, edit vm pool always points to the first logical storage domain. (edit pool->resource allocation->disks allocation). When increase VMs to the pool the disks will be allocated always in the first logical storage domain.
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
Verified with rhevm-4.0.2.3-0.1.el7ev.noarch. 1. Have 2 SDs in DC. 2. Created template. 3. Copied template disk to 2nd SD. 4. Created vm pool: in resource allocation->disks allocation choose the 2nd logical SD. 5. Edit vm pool: increase by 1 vm, verified that in 'esource allocation->disks allocation' the SD is still the 2nd. 6. Verified the new vm was created under the 2nd SD.
