Thanks Maor,in non ovirt kvm setup i use GFS2 to make the block

shareable across multiple hosts.Could you tell me how is it achieved
in ovirt.
When using iSCSI, they are not shared.
You have to make sure your storage infrastructure allows multiple
connection to the iscsi LUN.
But there is nothing to do about sharing on the block level.
When migrating data in iSCSI environement, according to what I've
witnessed, blocks are dd'ed (so this takes time) from the SD source to
target.
I guess that's where glusterfs adds some benefit.
