<p><b>New page</b></p><div>= Virtio-SCSI =<br />
VirtIO SCSI is a new para-virtualized SCSI controller device for KVM instances.<br />
It has been designed to replace virtio-blk, increase it's performance and improve scalability.<br />
The interface is capable of handling multiple block devices per virtual SCSI adapter,<br />
keeps the standard scsi device naming in the guests (e.x /dev/sda) and support SCSI devices passthrough.<br />
<br />
== Image properties ==<br />
The SCSI controller model can be set to virtio-scsi by proving<br />
the hw_disk_bus_model=virtio-scsi property in Glance<br />
image metadata. Otherwise, libvirt will automatically configure it's default model.<br />
<br />
<pre><nowiki><br />
glance image-update \<br />
--property hw_scsi_model=virtio-scsi \<br />
[image]<br />
</pre></nowiki><br />
<br />
== Virtual Devices ==<br />
All virtual devices which has it's bus set to "scsi" will be tied to this controller.<br />
Currently the following properties can be set to scsi, together with the hw_scsi_model:<br />
hw_cdrom_bus<br />
hw_disk_bus<br />
hw_floppy_bus</div>
