oracle linux 9.1 missing rhel-9.xml in /usr/share/osinfo/os/
osinfo-query os
shows warning "Entity redhat.com/rhel/9 referenced but not defined".
It affects at least virt-install and virt-manager - they can't create VM.
In /usr/share/osinfo/os/ i copied rhel-9-unknown.xml to rhel-9.xml and fixed ids and it helped.
Using libosinfo-1.9.0-5.el9.x86_64 from ol9_appstream.
