[one-users] LVM over iSCSI or NFS for OpenNebula

Are you using virtio drivers? I also recommend playing with the 'cache'
parameter. How well does it perform compared with I/O operations in the
hypervisor? Is the storage the problem here or the Virtualization layer?

have you set up cLVMd? I think for your setup the best approach is:
http://docs.opennebula.org/4.10/administration/storage/fs_lvm_ds.html

Or something like GFS2.

cheers,
Jaime
