Related QEMU commands under fedora 20: yum install libvirt yum install tunctl tunctl -b ip link set tap0 up brctl addif virbr0 tap0 ./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \ -kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \ -no-reboot -append "console=ttyUL0,115200 doreboot" -nographic \ -net nic,vlan=0,model=xlnx.xps-ethernetlite,macaddr=00:16:35:AF:94:00 \ -net tap,vlan=0,ifname=tap0,script=no,downscript=no in microblaze qemu bash (guest machine): ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0 ifconfig eth0 up After add this patch, can find the device, and can be used by 'telnetd' (need cross-build busybox with glibc for it), then outside can telnet to it without password.
