Hii Berto, Thanks for the inputs. As suggested by you i tried "qemu-system-aarch64 --help | grep helper" which showed the path as /usr/local/libexec/qemu-bridge-helper, but similar output.
Also i compiled the qemu 5.2.0 and used the following command - qemu-system-aarch64 -machine vexpress-a15 -cpu cortex-a57 -m 1G -kernel ifs/aarch64/$IFSNAME -drive file=fs/aarch64/fs.qcow2,if=none,id=drv0 -device virtio-blk-device,drive=drv0 -netdev bridge,br=virbr0,id=net0,helper=/home/asif/qemu_test/qemu-5.2.0/qemu-5.2.0/build/qemu-bridge-helper -device virtio-net-device,netdev=net0,mac=$MACADDR -nographic -serial mon:stdio giving error as - failed to parse default acl file `/home/asif/qemu_test/qemu-5.2.0/qemu-5.2.0/build/../etc/qemu/bridge.conf' qemu-system-aarch64: bridge helper failed Any inputs on this ? How can i resolve failed to parse default acl file ?
