The problem was nova delegates creating port to os-vif and it creates VIFGeneric interface which is ethernet interface type instead of bridge interface type in libvirt xml.

# virsh dumpxml 1 |grep -A5 '<interface '
    <interface type='ethernet'>
      <mac address='fa:16:3e:e3:35:c0'/>
      <target dev='tap94a85fd4-e1'/>
      <model type='virtio'/>
      <mtu size='1450'/>
      <alias name='net0'/>

For temporary fix, I modified nova/virt/libvirt/vif.py to use bridge interface type and rebuild the image - docker.io/jijisa/nova:skb-yoga-ovspatch-ubuntu_jammy

Change nova-compute image to this image and stop/start VM. Then, a bridge interface type will be set in libvirt xml like this.

   # virsh dumpxml 2 |grep -A11 '<interface '
       <interface type='bridge'>
         <mac address='fa:16:3e:e3:35:c0'/>
         <source bridge='br-int'/>
         <virtualport type='openvswitch'>
           <parameters interfaceid='94a85fd4-e142-4354-b49e-9f556fcbc9e5'/>
         </virtualport>
         <target dev='tap94a85fd4-e1'/>
         <model type='virtio'/>
         <mtu size='1450'/>
         <alias name='net0'/>
         <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
       </interface>
