Example

<disk type="block" device="disk">
    <driver name="qemu" type="raw" cache="none" io="native" iothread="1"/>
    <source dev="/dev/mapper/36005076305ffc1ae00000000000021d7"/>
    <target dev="vdb" bus="virtio"/>
    <address type="ccw" cssid="0xfe" ssid="0x1" devno="0xa30e"/>
    <boot order="1" loadparm="2"/>
</disk>

Note: Make sure the device with boot order="1" is valid and accessible before you start the virtual machine. On IBM Z, if the device with boot order="1" is not valid, the virtual machine does not try the next device and fails to boot.
