You've set the same hwaddress (mac-address) for both bridges - this is wrong (in almost all sensible configurations):
* use the mac-address of ens26f2 for vmbr0
* use the mac-address of either ens26f0 or ens26f1 for both bond0 and vmbr1
* you can find the mac-addresses in the output of `ip link`
I hope this helps!
