nathanejohnson commented on issue #2341: CLOUDSTACK-10160: Fix typo in Libvirt XML definition
for Virtio-SCSI
URL: https://github.com/apache/cloudstack/pull/2341#issuecomment-347239837
 
 
   @wido when using linux, it recognizes as a VIRTIO-Scsi HBA, and when spinning up Windows
guests with the Virtio SCSI drivers installed it recognizes the storage appropriately.  That
doesn't "prove" it's actually using it as virtio-scsi, but it's possible when the "model"
is not specified (or incorrectly specified) it might default to "auto", which might do the
right thing based on OS support?  I'm guessing here.

> The XML for defining Virtio-SCSI has a typo:
> It defines:
> *<controller type='scsi' index='0' mode='virtio-scsi'>*
> But this should be
> *<controller type='scsi' index='0' model='virtio-scsi'/>*
> Sources:
> - https://libvirt.org/formatdomain.html#elementsControllers
> - https://www.redhat.com/archives/libvirt-users/2014-February/msg00011.html
> A scsi controller has an optional attribute model, which is one of 'auto', 'buslogic',
'ibmvscsi', 'lsilogic', 'lsisas1068', 'lsisas1078', 'virtio-scsi' or 'vmpvscsi'.
