Reco, 

Thanks for the reply.

Thanks.  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.  (?)

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.
