I ignored the validation here 'i' (thanks Michal Privoznik for the
suggestion on IRC -- this looks like something to do with some XML
validation work from Martin Kletzander), and went ahead to test the
actual bug this patch fixes: 

It works: 

  A guest  w/ 'nvmram' XML element as below:

   $ virsh dumpxml node2 | grep -i nvram  -A2 -B3
      <os>
        <type arch='aarch64' machine='virt'>hvm</type>
        <loader readonly='yes' type='pflash'>/usr/share/AAVMF/AAVMF_CODE.fd</loader>
        <nvram>/var/lib/libvirt/nvram/fedora-21-aarch64-nvram</nvram>
        <boot dev='hd'/>
      </os>

  Can be undefined successfully.
