Wifi on macOs Big Sur vm

[N7ghtm4r3]

Hi, I've create a virtual machine with macOs installed, the Big Sur version, and it correctly boots but the networking, in the specific the wifi, doesn't connect successfully because does't find the any networks to connect.
I've read it is needed to use the bridge=br0 in the related .conf file but, also if the bridge has been created on the Ubuntu host machine, when I launch the vm doesn't boot with the message:

- Network:  Bridged (br0)
 - Monitor:  On host:  nc -U "macos-big-sur/macos-big-sur-monitor.socket"
             or     :  socat -,echo=0,icanon=0 unix-connect:macos-big-sur/macos-big-sur-monitor.socket
 - Serial:   On host:  nc -U "macos-big-sur/macos-big-sur-serial.socket"
             or     :  socat -,echo=0,icanon=0 unix-connect:macos-big-sur/macos-big-sur-serial.socket
cat: macos-big-sur/macos-big-sur.pid: No such file or directory
 - Process:  Starting macos-big-sur.conf as macos-big-sur ()

May I have wrong any steps to execute correctly with the bridge or it is possible don't use the brigde and connect directly from the vm machine? Thank you!
