Cannot select a bridge when creating a virtual machine

[sasha0552]

I have created a bridge, but cannot select it in the Installation source when creating a virtual machine with the Network Boot (PXE) Installation type.
Only lo, virtual networks, and physical NICs available.
I can create a VM using any of the physical NICs and it will use the (first?) bridge automatically instead of physical NIC.

I'm using Debian 12 with backports.

Network topology:

eth0 -\
eth1 -\
      bond0 -\
             br0 (DHCP)
