I eventually found the problem: all qemu instances will use the same MAC address for their NIC. When I set different MACs to the different VMs, everything works well: mac=52:54:0:0:0:1 # or 2, 3, ... ... -net nic,macaddr=${mac},model=${nic_model} -net tap \ -- __Pascal Bourguignon__ http://www.informatimago.com/
