From: Harshal Patil <harshalp(a)linux.vnet.ibm.com&gt; On s390x DASD type devices should not be shown by kimchi's host/partitions API if they don't have any partition. Such devices are not valid type devices for operations like pvcreate, which means we cannot show them to users who want to have them in storagepools based on LVM.
