qemu-kvm: bridge helper failed
[root@CentOS-82-64-minimal 23815135]# /usr/libexec/qemu-kvm -enable-kvm -boot order=cd,once=dc -vga cirrus -m 4096 -drive file=/root/kvmguests/23815135/23815135.img,if=virtio -usbdevice tablet -net nic,macaddr=DE:AD:BE:EF:D4:AB -netdev bridge,br=br0,id=net0
So you're trying to use a bridge are told you are being denied. Make sure you create a bridge.conf file and allow br0 or whatever your bridge device in that file and it will work after.
Solution:
mkdir -p /etc/qemu
echo "allow br0" >> /etc/qemu/bridge.conf
Remember those also requires that you have a bridge called br0, here is a guide for the bridge.
