Daan, Could you cherry-pick the commit "cd414a0f56798ae801fc464be127e37daabef809" into 4.4? This is a fix to the bug CLOUDSTACK-6935.
Bug description: Some storage pool filtering logic like hypervisor type check, storage type check for root volume and avoid list check is not enabled in ZoneWideStoragePoolAllocator. Regards, Noji
