Reco, Thanks for the reply.

I'm trying to set a _static_ address for the guest. https://en.wikipedia.org/wiki/Static_ip_address Ref. https://lists.debian.org/debian-user/2021/03/msg00546.html All the QEMU documentation I've found focusses on DHCP. Imagine the guest system tries to set a static address and QEMU offers DHCP. Seems unlikely to succeed. Should be a way to configure qemu to provide a subnet to the guest on an interface with a static address. (?) > Of course, as it's not a point-to-point connection. Yes, but a stanza in /etc/network/interfaces refers to an interface name. The Debian 10 here for example, includes interface enx0050b60be9be which is used for a subnet. To make a valid stanza for the qemu guest an interface name is essential. Either qemu must invent a name or the qemu configuration will have to specify it. Another detail I haven't found in the documentation. Thanks, ... P. -- cell: +1 236 464 1479 Bcc: peter at easthope. ca VoIP: +1 604 670 0140
