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.
