You can try and these to see if something is shown in the guest.

yes, for those who might stumble upon this/similar - it 
turns out to be the structure declaration in xml
 ? <qemu:commandline>
VS
 ? <commandline>
of whose the latter _works_ ! on centos 9 with 
libvirt-daemon-9.0.0-7.el9.x86_64 but not the former.

@devel - should this go as BZ report into bugzilla?

Did you declare the appropriate XML namespace?:

  <domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
