KVM.

As I  said elsewere,  clusters can become  unstable without  a fencing
device (and possibly without a proper sysadmin), but this is **totally
outside** OpenNebula or libvirt  responsibility.

When you have a good cluster yuo could achieve better performances.

OpenNebula team could start thinking about supporting directly an even
better solution, the clustered lvm (that's under clustered gfs anyway):

Bot front  end and nodes see  the same clustered volume  group through
iSCSI/fiberchannel   and    the   frontend   governs    remotely   the
mounting/unmounting  of  the  logical volumes  during  migrations  and
logical volumes distructions.

This does not cover  ALL the LVM usages, but for  sure covers the most
useful configuration for a clustered volume group on a SAN.
