Enable the Use of a SCSI Controller

Create an XML file for the SCSI controller. In this example, it is called virt-scsi.xml.

[root@localhost~]# 
cat /root/virt-scsi.xml 

<controller type='scsi' index='0' model='virtio-scsi'> 
<address type='pci' domain='0x0000' bus='0x00' 
slot='0x0b'function='0x0'/> 
</controller> 

Make sure that the slot used for the virtio-scsi controller does not conflict with another device.

Associate this controller with the XML template of the VM-Series firewall.

[root@localhost~]# 
virsh attach-device 
--config 
<VM-Series_name>/root/virt-scsi.xml

Device attached successfully 

Enable the firewall to use the SCSI controller.

[root@localhost~]# 
virsh attach-disk 
<VM-Series_name>/var/lib/libvirt/images/PA-VM-8.1.0.qcow2 
sda --cache none --persistent 

Disk attached successfully 

Edit the XML template of the VM-Series firewall. In the XML template, you must change the target disk and the disk bus, used by the firewall.

By default, the XML template is stored at etc/libvirt/qemu.

<disk type='file' device='disk'> 
      <driver name='qemu' type='qcow2' cache='writeback'/> 
      <source file='/var/lib/libvirt/images/PA-VM-8.1.0.qcow2'/> 
      <target dev='sda' bus='scsi'/> 
      <address type='drive' controller='0' bus='0' target='0' unit='0'/> 
</disk>
