(If you have a proxmox7 server to test, I can provide you some test .deb packages)



The mac address prefix option at datacenter level, is prefix when you autogenerate mac address for the vms.

if you want test on proxmox7, download this deb:

https://mutulin1.odiso.net/libpve-common-perl_7.0-6_all.deb
https://mutulin1.odiso.net/libpve-network-perl_0.6.1_all.deb (optionnal, only if you use the sdn beta feature)
https://mutulin1.odiso.net/pve-container_4.0-9_all.deb (only if you use containers)
https://mutulin1.odiso.net/qemu-server_7.0-13_amd64.deb (only if you use vms)

and install them with "dpkg -i *.deb".

then, edit /etc/network/interfaces,

and under the vmbrX bridge, add "bridge-disable-mac-learning 1"

Code:
auto vmbr0
iface vmbr0 inet manual
        bridge ports ...
       ...
        bridge-disable-mac-learning 1

Then, reboot.

That's all.
