Thank you, Gianluca.
The OpenStack integration with ScaleIO absolutely warrants further investigation on my
part. It looks like a rather recent addition to ScaleIO, so I'll need to run that in a
lab setting for a while. It looks like the best long term option.
In the meantime, I think that I might be able to get this working by exposing a few,
larger LUNs via NFS running on the ScaleIO nodes. I lose granular snapshot capabilities
and MPIO in ScaleIO that way, though.
If I need real MPIO-type performance on a VM, I guess I can just install the ScaleIO
client in the guest and access the LUN that way.
Also, I plan on learning more about the iSCSI Direct LUN logic in oVirt to see if there is
enough similarity between the output of iscsiadm and the ScaleIO SDC/SDS utilities to
request a direct ScaleIO integration feature. That might be a nice little side project for
a while.
Have a great day,

I was thinking that I would just set up iSCSI LUNs in ScaleIO and have oVirt point
directly to one for the hosted engine setup. From there, my plan was to assign disks to
VMs as direct LUNs.
Unfortunately, it looks like ScaleIO dropped iSCSI support at around version 1.32 and
I'm at a loss as to how I can expose ScaleIO LUNs to oVirt.
Thank you,

I don't know much of ScaleIO, but at least since Liberty release it can be configured
as a cinder backend driver in Openstack
http://docs.openstack.org/liberty/config-reference/content/ScaleIO-cinder...
http://docs.openstack.org/mitaka/config-reference/block-storage/drivers/e...
So the more "natural" way that comes to mind is to interface oVirt with cinder
and configure ScaleIO in cinder in similar way as with Ceph backend
http://old.ovirt.org/Features/Cinder_Integration
But this implies configuring Openstack too and also I don't know how the security part
(see ceph authentication in above link), if present in ScaleIO, could be managed
