when attaching an iscsi volume (created via cinder) to a VM, is the iscsi stack needed on the VM or is it simply needed on the nova compute node which is running the VM?

It appears that it is not needed but I'd like to verify that I am correct

No, iscsi-initiator runs on the compute host but not inside the compute instances themselves.

actually tgt is the back-end device, the compute node is running iscsi-initiator. But in terms of it running only on the compute node you're correct. It's attached to the compute node and passed in to the instance via libvirt.
