Yes. The problem is the allocated mac addresses. I can't remember what the daemon does precisely but I don't remember it doing auto-mac address allocation. Anyway, try: guestkernel ... eth0=tuntap,,fe:fd:00:00:00:01, because as you point out, you don't need the address at the end because you're using DHCP. What I do to get different addresses is to have each UML send a local (on the host OS) DHCP server the host name, or a dhcp-client-identifier which is different for each VM. The VMs still can't see each other though; not unless they're mac addresses are different. I have another virtualization system that needs unique mac addresses and what I do is map the mac address from a per-vm instance id. That is inefficient because the VM instances might be short lived so in the future I'll be writing a mac address allocator for UML which will work on a pool of addresses and possibly work over a network (allowing several host OS to share a pool). This is a complex task though so it will take me a little while before I get round to it. -- Nic Ferrier http://www.tapsellferrier.co.uk for all your tapsell ferrier needs ------------------------------------------------------------------------- Using Tomcat but need to do more?
