[one-users] additional parameters for the DISK section

[João Pagaime]

Hello Ruben

that's right....  TARGET doesn't seem to be working (at least with SCSI)

here's a quick example:

------------- open-nebula template:
..........
DISK=[
  DRIVER="raw",
  IMAGE_ID="82",
  READONLY="no",
  TARGET="sda" ]
DISK=[
  DRIVER="raw",
  IMAGE_ID="83",
  READONLY="no",
  TARGET="sdb" ]

------------- libvirt generated  template:
..............
                <disk type='file' device='disk'>
                        <source file='/var/lib/one//datastores/0/931/disk.1'/>
                        <target dev='sda' bus='scsi'/>
                        <driver name='qemu' type='raw' cache='default'/>
                </disk>
                <disk type='file' device='disk'>
                        <source file='/var/lib/one//datastores/0/931/disk.2'/>
                        <target dev='sdb' bus='scsi'/>
                        <driver name='qemu' type='raw' cache='default'/>
                </disk>

-------------- error:
......
process exited while connecting to monitor: kvm: -device
lsi,id=scsi0,bus=pci.0,addr=0x4: Parameter 'driver' expects a driver
name


best regards,
João
