Denies/log entries and their related solution:

XML snippet generated:
    <graphics type='spice'>
      <listen type='none'/>
      <image compression='off'/>
      <gl enable='yes'/>
    </graphics>
(no rendernode set and no other gl reference got added).

Generated profile (did gl detection trigger?):
Has no references to rendernodes that should be added by virt-aa-helper

guest log fails as almost expected:
