Hello all, I would like to install Debian Bullseye using virt-install, as part of the command I usually specify the OS used with the option '--os-variant'. This works great untill Buster ('debian10'), but now the guest is Bullseye ('debian11') and is not listed in the output of 'osinfo-query os' (1). If I don't use the '--os-variant' flag I get the following warning: "WARNING  No operating system detected, VM performance may suffer. Specify an OS with --os-variant for optimal results." Should I ignore the warning or what is the best way forward to install a Debian Bullseye guest? Both the host and the guest are  Debian 11. 1)  https://lists.debian.org/debian-user/2021/12/msg00742.html

Alternatively, you can install a newer version of the osinfo database by using osinfo-db-import. Doing so is probably overkill for your use case. Pino, do you think it would make sense to rebase osinfo-db in the next Debian 11 update? Or at least cherry-pick the debian11 entry so that things work as expected when creating a Debian 11 VM on a Debian 11 host? https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980744 was AFAICT intended to achieve just that.

I don't think there's a specific reason for that, it's probably just a matter of nobody thinking of it until now :) In addition to that, considering that there already entries for Debian testing and Fedora Rawhide, adding one for Debian unstable might make sense too.
