Hi, I can start my freebsd based image in Qemu, and I use tap interface for connectivity to the host or external world, but when I try to fire up 2 instances, using tap, it fails. For the second invocation, it gives me the error: address@hidden tmp]# ./qemu-system-x86_64 -m 512 anjali.img -net nic,model=yukon,macaddr=52:54:00:00:aa:02 -net tap,ifname=tap0,script=no warning: could not configure /dev/net/tun: no virtual network emulation Could not initialize device 'tap' Am I doing something wrong? The first instance is running fine.
Please make sure your instances have different mac address. The following settings might work: Instance 1: macaddr=52:54:00:00:aa:02 Instance 2: macaddr=52:54:00:00:aa:03 Thanks Shan Hai
