So I assume what you wrote about "software iscsi target and initiator gives
me high cpu load on both domU and target" was from a different setup,
and that FreeNAS with zfs gives acceptable performance, right?

Something like that. Whatever shared storage you use, it needs to be
available on all dom0s. For iscsi, this means importing all iscsi
shares and reference them on dom0 using a common path on all dom0s
(/dev/disk/by-path or by-id should be good).
As an alternative, there's a block-iscsi helper script (try google
search) that can be used easily.

On all shared storage setup, you have to make sure that domUs only
started on one dom0 at a time. You can use some tools to do this (like
linux cluster's rgmanager) or (when you only have several domUs) it
might be pereferable to do it manually.
