[one-users] error when attach disk

[Tino Vazquez]

Hi,

This is a known issue with that libvirt version. In order to
circumvent this behaviour, you need to:

* Use a VM with the OS disk set to IDE (DEV_PREFIX="hd" needs to be
present in the image template)
* Use SCSI image to attach (DEV_PREFIX="sd" needs to be present in the
CDROM image template)
* Use a VM with a virtio SCSI controller stated in the RAW section:

RAW=[
DATA="<devices><controller type='scsi' index='0'
model='virtio-scsi'></controller></devices>",
TYPE="kvm" ]

Regards,

-Tino
