DHCP is an option for a network configuration, not a requirement. If you don't like guest OS to be configured by DHCP, you're welcome to use /e/n/i snippet that I referenced in my previous e-mail. > Should be a way to configure qemu to provide a > subnet to the guest on an interface with a static address. (?) Please clarify. Where exactly you need a static address to be configured? At the guest OS's NIC? At the QEMU's emulated gateway?

Ok, but surely it's a little problem to replace "eth0" with "enx<gibberish>", isn't it? > To make a valid stanza for the qemu guest an interface name is > essential. I agree. > Either qemu must invent a name It's definitely does not work this way. QEMU has no way to specify an exact name for the guest OS. > or the qemu configuration will have to specify it. Nope. QEMU's job is to run unmodified guest OS, no more and no less. Specific OS implementation details (such as NIC names) are left to the specific OS to handle. > Another detail I haven't found in the documentation. QEMU's documentation is an unsuitable place to describe OS-specific implementation details. Try [1], chapter 4, instead. Reco [1] https://wiki.debian.org/NetworkInterfaceNames
