I was trying to use virt-install to install a SLES 12 server GM VM to a DASD on system z, with KVM as hypervisor. However during the YaST2 installation, in the "disk activation" phase, it doesn't detect the DASD. So no DASD option is proposed. When ignoring this, I could continue till the installation finishes. However, the guest never reboots. Any thoughts about this issue?
