I've installed ubuntu 20.04 on WSL2 and I started a VM with qemu and kvm,running mac os x as guest os. It works great,except for the configuration of the net. Infact it is not able to connect to internet. Sometime from WSL I get a 192.x.x.x ip number,like :
192.168.69.65 ; 192.168.71.185 ; 192.168.73.223 ; 192.168.69.33 ; 192.168.100.101
sometime I get a 172.x.x.x ip address,like : 172.22.250.54 ; 172.22.253.128 ; 172.21.138.120 ; 172.22.88.142.
The vEthernet (WSL) adapter on Windows 10 is configued like this : 172.26.80.1 as IP address,subnet mask = 255.255.240.0
I have created a bridge in WIndows 10,between my Intel ethernet adapter and the tap0 / Tap-windows. It's IP is 192.168.1.6 ; subnet mask = 255.255.255.0 ; gateway = 192.169.1.1 ; dns primary = 8.8.8.8
I have configured WSL like it is explained,but it didn't work. Check below what happens :

I dont know why after removing address from eth0, which had an ipv4 address, and creating a bridge,it becomes no ipv4.
