My question is very similar to this. But it didn't help me. I have some Qemu KVM virtual machines (CentOSs and Debians mostly) and my host is an Ubuntu. I configured the VMs networks with virtio virbr0, and I also made it work by creating a virtual interface, connecting the VMs to that virtual interface (dolling out IPs with dnsmasq) and NATing traffic through the host.
Now, for the purposing of learning, I really wanted to create a bridge, add my wifi interface as one of the ports and connect my VMs into the bridge, but I wasn't successful. As the guy referred above, I also used Debian's bridge tutorial to try to make ebtables "masquerade" my VM MAC address (as the AP won't accept a different MAC from the one that previously authenticated). But my problem is that I couldn't even add my wifi as the bridge port.
my /etc/network/interfaces:
auto lo
iface lo inet loopback
# this is my wifi card (god knows why udev gave this name)
auto wlx44334c371663
iface wlx44334c371663 inet manual
# of course I added my wifi real MAC in bridge_hw option
