I.e. you want to talk from the host to the guest via IP, right? You're describing it as if it were an extraordinary thing and this is causing in you more confusion than needed. > So a bridge looks likely (anyone think of a creative other way?) You don't need a bridge at all. Somebody uses a bridge to setup dozens of UMLs with little work and without installing setuid applications (i.e. uml_net in uml-utilities). But that's not needed. Look at http://user-mode-linux.sourceforge.net/networking.html, and choose TUN/TAP with the uml_net helper. You'll also need to assign a MAC to the interface,via: Use eth0=tuntap,,fe:fd:0:0:0:1,$hostip, and choose different MACs (leave the form fe:fd:x:x:x:x). > I'm quite happy to run a local dhcp server and provide addresses to > UMLs, > But having a bridge on a laptop is problematic. Laptop network > hardware is loaded in a variety of ways: hotplug, kernel, modules, ppp > interfaces etc... What are you talking about? What you say does not make sense. hotplug, kernel and modules don't give any load on "laptop network hardware". Especially not hotplug. And running a bridge isn't an heavy (resource-wise) task at all. The only valid interpretation I can form is that bridging together a ppp interface with all the rest is not a good idea, which is true, but on a software bridge you add only the interfaces you choose (I now realize this is non-obvious thinking to an hardware bridge). -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
