[perhaps solved] qemu kvm ( tap )

i think qemu's difficulty lies in network.

i managed to work qemu ~ kvm.

1)cat /etc/netctl/bridge
Description="Example Bridge connection"
Interface=br0
Connection=bridge
BindsToInterfaces=(enp2s0 tap0)
IP=dhcp

2) cat /etc/qemu-ifup
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /usr/bin/ip link set $1 up promisc on
echo "Adding $1 to br0..."
sudo /usr/bin/brctl addif br0 $1
sleep 2

3)cat /etc/qemu-ifdown
#!/bin/sh
echo "Executing /etc/qemu-ifdown"
sudo /usr/bin/ip link set $1 down
sudo /usr/bin/brctl delif br0 $1
sudo /usr/bin/ip link delete dev $1

4) cat qemu-Memory-Image.bat ------- this is a shell script

modprobe tun
sysctl net.ipv4.ip_forward=1
systemctl start libvirtd
netctl start bridge
qemu-system-x86_64 -enable-kvm -m $1 -hda $2 -net nic,macaddr=52:54:00:12:11:11 -net tap,ifname=tap0,script=/etc/qemu-ifup
netctl restart bridge

example
./qemu-Memory-Image.bat  1024  openbsd.img
