Is this correct behavior, or is this a qemu or guest OS bug? If it's something
that's going to be fixed eventually I'd rather not add it to virtinst. Is
there a bug report somewhere I can look at?
described in below.
1. qemu-img create -f qcow2 /var/lib/libvirt/images/sle.qcow2 20G
2. cat sle1.xml
[root@ltczhp20 ~]# cat sle.xml
.....
<os>
<type arch='s390x' machine='s390-ccw-virtio-2.6'>hvm</type>
<boot dev='hd'/>
</os>
<clock offset='utc'/>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<emulator>/usr/bin/qemu-kvm</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/sle.qcow2'/>
<target dev='vda' bus='virtio'/>
<address type='ccw' cssid='0xfe' ssid='0x0' devno='0x0000'/>
</disk>
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<target dev='sda' bus='scsi'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>

3. virsh create sle1.xml
4. virsh start sle1 --console
infinite loop message: .... Using guessed DASD geometry. Using ECKD scheme (block size 4096), CDL ! No zIPL section in IPL2 record. !
