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.


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Alternatively, you can install a newer version of the osinfo database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.

Any reason for debian not having an -unknown version like lot of the
other distros?
