You can just use '--os-variant debian10', it will work fine.

Alternatively, you can install a newer version of the osinfo database
by using osinfo-db-import. Doing so is probably overkill for your use

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? was
AFAICT intended to achieve just that.
