Hi,
I would like to understand the local storage purpose.
I was wondered are there any production systems using local storage?
Or in another way, how to use effectively the local hosts disks?
My ovirt purpose is so serve HA-VM LAMPs.
Thanks,
Arman.

Well yes there is local storage in production at various sites.
For real HA you inevitable need a shared storage solution.
You could try to utilize local disks by using gluster ceph
or any other software defined storage system.
Gluster is the most integrated withing ovirt, but here are some
caveats:
It's not encouraged to run vms on the hosts which are part of the
gluster cluster (but it works, at least this is what you can read on
this very ML).
It's not supported to run hosted-engine on top of gluster, at least
not without a replica count of at least 3.

An example and
'real' use case to Svens answer:
The term 'local' might indeed a bit misleading. The posix file system
option basically lets you use anything posix compliant. For instance I
am using a cluster file system called StorNext in our company - witch is
very well suited for use with oVirt. Without POSIX, I could not have
used it.

or any other software defined storage system.

Posix enables usage of GlusterFuseFS.
However, it might be the case the
replica 3 is only needed when using FuseFS [1], independent from the
fact of using Gluster and Compute on the same host.
