Comment 6 for bug 2062168

Thank you, setting "nova::compute::libvirt::services::modular_libvirt: true" and "nova::migration::libvirt::modular_libvirt: true" fixed the issue. As in EL9 the modular libvirt seems to be the defult, I proposed it as a change in https://review.opendev.org/c/openstack/puppet-nova/+/920722. Let me know what do you think about it
