hi, while this patch should work (did not test it),
this can be done better

we could do something like:

---8<---
for (my $id = 0; $id < MAX_NETS; $id++) {
    my $iface = "net$id";
    next if !$conf->{$iface};
--->8---

this way we do not have to grep the whole conf
and sort it afterwards, but have it always sorted by default

(i know the code is not from you, but when we fix
this, we could as well clean it up :) )

where MAX_NETS comes from PVE::QemuServer (somehow)

would you be willing to send a v2 with such a change,
or would you prefer if i send it ?

btw, please see the note about the CLA if you did
not already sent one
