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

Hello All, I am using NFS as shared storage and is working fine,able to migrate instances across nodes. Is it possible to use iscsi backend and achieve the same,a shared iscsi[i am not able to find a way to do a shared iscsi across hosts] can some one help with a shared iscsi storage for live migration of vm across hosts

Hi,
What do you mean by shared iscsi? if you created a new iSCSI Storage Domain in the Data Center and it is active then all the hosts should see it while it is Active.
