I can start my freebsd based image in Qemu, and I use tap interface for

instances, using tap, it fails. For the second invocation, it gives me the

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
