virt-v2v doesn't support export from RHEV, only import. However, it
doesn't sound like you need V2V here. Once you've exported the VM to an
export storage domain, you can simply back up the files in the export
storage domain. tar would work as well as anything else here.

Exporting a libvirt or ESX VM which use iscsi for storage should work
If you're exporting *to* RHEV, we can only write to an NFS export
storage domain. However, when you import this guest into RHEV, it can be
written to any storage, which would include iscsi.

virt-v2v -ic xen+ssh://xen.server/ -o rhev -osd rhev.nfs.server/export
