Description Daniel Erez 2013-10-02 08:33:05 UTC 
A new 'VirtIO-SCSI enabled' flag should be introduced in order to support enabling/diasabling VirtIO-SCSI controller attachment (on VM level).

When enabled, a controller is attached automatically when running the VM.
That way, hot-plugging a disk attached with VirtIO-SCSI interface is applicable.
When disabled, all VirtIO-SCSI functionality is blocked for the relevant VM (from UI/backend).

Note: for cluster >= 3.3, the flag is defaulted to true.

<vm>
   <cluster><name>ISCSI</name></cluster>

   <name>Vm04</name>
   <virtio_scsi enabled="false"/>
</vm>


in case false we can't attach virtio-scsi disk,
