Re: [Qemu-discuss] FreeDOS in qemu: no internet-connection

[Donald R Laster Jr]

Christian,

  Try this (1.4.x):

        -net nic,macaddr=52:54:00:10:01:1F,vlan=0,model=e1000 -net 
tap,vlan=0,helper=/usr/libexec/qemu-bridge-helper

or this (2.12.x/3.0.x):

        -nic 
tap,mac=52:54:00:10:02:02,model=e1000,helper=/opt/vms/qemu/qemu_2.12.0/libexec/qemu-bridge-helper

or a various of these. These are what I have in use.

   Don
