This one line should enable the tap device: -nic tap,model=lance,ifname=tap0 Did you configure the guest? There are some hints here how to set up the router etc.: https://en.wikibooks.org/wiki/QEMU/SunOS_4.1.4 Best, Howard

add vEthernet to QEMU
Hi, I am starting QEMU with option *-netdev tap,id=mynet0,ifname=TAP_Ethernet,script=no,downscript=no* TAP_Ethernet is a TAP Windows Adapter v9 created using openVPN. by this way, i am able to send data from windows to QEMU through TAP adapter. similarly, can i have Hyper-V Virtual Ethernet Adapter associated to QEMU? Thanks & Regards, Sanjeev.
