[ovirt-users] Ovirt & Ceph

[rajatjpatel]

Great, thanks! Alessandro ++ Yaniv ++

What I want to use around 4 TB of SAS disk for my Ovirt (which going to be
RHV4.0.5 once POC get 100% successful, in fact all product will be RH )

I had done so much duckduckgo for all these solution and use lot of
reference from ovirt.org & access.redhat.com for setting up a Ovirt engine
and hyp.

We dont mind having more guest running and creating ceph block storage and
which will be presented to ovirt as storage. Gluster is not is use right
now bcoz we have DB will be running on guest.

Regard
Rajat
