It works with both hostgroup and targetgroup starting the VM provided
that you add -iscsi 'initiator-name=<initiator-name>' since this option
will be transferred to libiscsi. The problem is qemu-img which is used
extensively in storage scripts in proxmox. It might be worth trying to
make a feature request to the qemu-img team to add this option?

No, I haven't tried this but I think we should keep both hoping for
qemu-img team to add the feature. Until then we simply ignore the
option.

Your patch still needs to handle the case where a VM has been converted
to a template since image handling after conversion complains of an
unknown setting: sparse.
