I can't get Qemu 4.1.0 to make a network connection using Win 10 as a client under TW. Qemu 3.1.1.1 works fine under TW. The 4.1 under under 15.1 works also. All with the same image.

This my command line:

qemu-system-x86_64 -snapshot -name telewerken -cpu phenom -smp cores=2,threads=1,sockets=1 -enable-kvm -machine type=q35,accel=kvm -m 3072 -soundhw hda -net nic,model=virtio-net-pci,macaddr=52:54:63:1f:a0:00 -net tap,ifname=tap0,script=/etc/qemu/qemu-ifup,downscript=/etc/qemu/qemu-ifdown -vga std -display gtk -rtc clock=host,base=localtime -boot order=c -usb -device usb-tablet -drive file=./telewerken.raw,format=raw,index=0,media=disk,if=virtio,cache=writeback

configuring qemu network with bridge for tap0 qemu-ifdown: Removing tap0 from Bridge br0 + sudo /sbin/tunctl -d tap0

Works already several years under TW,, 15.1 and pevious versions. It stopped working since the end of the summer when switching to kernel 5.1+(?)

Suggestions?
